- MISSION STATEMENT
- =================
-
- - Easy to use to create code-driven and data-driven tools.
- - Easy to use to create ad hoc short-lived tools and long-lived, more elaborate tools.
- - Easy to hack and improve.
- - Minimize setup and maintenance.
- - Minimize state storage on user side.
- - Minimize state synchronization.
- - Portable, minimize dependencies, run on target (consoles, phones, etc.).
- - Efficient runtime and memory consumption.
-
- Designed primarily for developers and content-creators, not the typical end-user!
- Some of the current weaknesses (which we aim to address in the future) includes:
-
- - Doesn't look fancy.
- - Limited layout features, intricate layouts are typically crafted in code.
-
-
- CONTROLS GUIDE
- ==============
-
- - MOUSE CONTROLS
-   - Mouse wheel:                   Scroll vertically.
-   - SHIFT+Mouse wheel:             Scroll horizontally.
-   - Click [X]:                     Close a window, available when 'bool* p_open' is passed to ImGui::Begin().
-   - Click ^, Double-Click title:   Collapse window.
-   - Drag on corner/border:         Resize window (double-click to auto fit window to its contents).
-   - Drag on any empty space:       Move window (unless io.ConfigWindowsMoveFromTitleBarOnly = true).
-   - Left-click outside popup:      Close popup stack (right-click over underlying popup: Partially close popup stack).
-
- - TEXT EDITOR
-   - Hold SHIFT or Drag Mouse:      Select text.
-   - CTRL+Left/Right:               Word jump.
-   - CTRL+Shift+Left/Right:         Select words.
-   - CTRL+A or Double-Click:        Select All.
-   - CTRL+X, CTRL+C, CTRL+V:        Use OS clipboard.
-   - CTRL+Z, CTRL+Y:                Undo, Redo.
-   - ESCAPE:                        Revert text to its original value.
-   - On OSX, controls are automatically adjusted to match standard OSX text editing shortcuts and behaviors.
-
- - KEYBOARD CONTROLS
-   - Basic:
-     - Tab, SHIFT+Tab               Cycle through text editable fields.
-     - CTRL+Tab, CTRL+Shift+Tab     Cycle through windows.
-     - CTRL+Click                   Input text into a Slider or Drag widget.
-   - Extended features with `io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard`:
-     - Tab, SHIFT+Tab:              Cycle through every items.
-     - Arrow keys                   Move through items using directional navigation. Tweak value.
-     - Arrow keys + Alt, Shift      Tweak slower, tweak faster (when using arrow keys).
-     - Enter                        Activate item (prefer text input when possible).
-     - Space                        Activate item (prefer tweaking with arrows when possible).
-     - Escape                       Deactivate item, leave child window, close popup.
-     - Page Up, Page Down           Previous page, next page.
-     - Home, End                    Scroll to top, scroll to bottom.
-     - Alt                          Toggle between scrolling layer and menu layer.
-     - CTRL+Tab then Ctrl+Arrows    Move window. Hold SHIFT to resize instead of moving.
-   - Output when ImGuiConfigFlags_NavEnableKeyboard set,
-     - io.WantCaptureKeyboard flag is set when keyboard is claimed.
-     - io.NavActive: true when a window is focused and it doesn't have the ImGuiWindowFlags_NoNavInputs flag set.
-     - io.NavVisible: true when the navigation cursor is visible (usually goes to back false when mouse is used).
-
- - GAMEPAD CONTROLS
-   - Enable with 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad'.
-   - Particularly useful to use Dear ImGui on a console system (e.g. PlayStation, Switch, Xbox) without a mouse!
-   - Download controller mapping PNG/PSD at http://dearimgui.com/controls_sheets
-   - Backend support: backend needs to:
-      - Set 'io.BackendFlags |= ImGuiBackendFlags_HasGamepad' + call io.AddKeyEvent/AddKeyAnalogEvent() with ImGuiKey_Gamepad_XXX keys.
-      - For analog values (0.0f to 1.0f), backend is responsible to handling a dead-zone and rescaling inputs accordingly.
-        Backend code will probably need to transform your raw inputs (such as e.g. remapping your 0.2..0.9 raw input range to 0.0..1.0 imgui range, etc.).
-      - BEFORE 1.87, BACKENDS USED TO WRITE TO io.NavInputs[]. This is now obsolete. Please call io functions instead!
-   - If you need to share inputs between your game and the Dear ImGui interface, the easiest approach is to go all-or-nothing,
-     with a buttons combo to toggle the target. Please reach out if you think the game vs navigation input sharing could be improved.
-
- - REMOTE INPUTS SHARING & MOUSE EMULATION
-   - PS4/PS5 users: Consider emulating a mouse cursor with DualShock touch pad or a spare analog stick as a mouse-emulation fallback.
-   - Consoles/Tablet/Phone users: Consider using a Synergy 1.x server (on your PC) + run examples/libs/synergy/uSynergy.c (on your console/tablet/phone app)
-     in order to share your PC mouse/keyboard.
-   - See https://github.com/ocornut/imgui/wiki/Useful-Extensions#remoting for other remoting solutions.
-   - On a TV/console system where readability may be lower or mouse inputs may be awkward, you may want to set the ImGuiConfigFlags_NavEnableSetMousePos flag.
-     Enabling ImGuiConfigFlags_NavEnableSetMousePos + ImGuiBackendFlags_HasSetMousePos instructs Dear ImGui to move your mouse cursor along with navigation movements.
-     When enabled, the NewFrame() function may alter 'io.MousePos' and set 'io.WantSetMousePos' to notify you that it wants the mouse cursor to be moved.
-     When that happens your backend NEEDS to move the OS or underlying mouse cursor on the next frame. Some of the backends in examples/ do that.
-     (If you set the NavEnableSetMousePos flag but don't honor 'io.WantSetMousePos' properly, Dear ImGui will misbehave as it will see your mouse moving back & forth!)
-     (In a setup when you may not have easy control over the mouse cursor, e.g. uSynergy.c doesn't expose moving remote mouse cursor, you may want
-     to set a boolean to ignore your other external mouse positions until the external source is moved again.)

-
- PROGRAMMER GUIDE
- ================
-
- READ FIRST
- ----------
- - Remember to check the wonderful Wiki (https://github.com/ocornut/imgui/wiki)
- - Your code creates the UI every frame of your application loop, if your code doesn't run the UI is gone!
-   The UI can be highly dynamic, there are no construction or destruction steps, less superfluous
-   data retention on your side, less state duplication, less state synchronization, fewer bugs.
- - Call and read ImGui::ShowDemoWindow() for demo code demonstrating most features.
-   Or browse https://pthom.github.io/imgui_manual_online/manual/imgui_manual.html for interactive web version.
- - The library is designed to be built from sources. Avoid pre-compiled binaries and packaged versions. See imconfig.h to configure your build.
- - Dear ImGui is an implementation of the IMGUI paradigm (immediate-mode graphical user interface, a term coined by Casey Muratori).
-   You can learn about IMGUI principles at http://www.johno.se/book/imgui.html, http://mollyrocket.com/861 & more links in Wiki.
- - Dear ImGui is a "single pass" rasterizing implementation of the IMGUI paradigm, aimed at ease of use and high-performances.
-   For every application frame, your UI code will be called only once. This is in contrast to e.g. Unity's implementation of an IMGUI,
-   where the UI code is called multiple times ("multiple passes") from a single entry point. There are pros and cons to both approaches.
- - Our origin is on the top-left. In axis aligned bounding boxes, Min = top-left, Max = bottom-right.
- - Please make sure you have asserts enabled (IM_ASSERT redirects to assert() by default, but can be redirected).
-   If you get an assert, read the messages and comments around the assert.
- - This codebase aims to be highly optimized:
-   - A typical idle frame should never call malloc/free.
-   - We rely on a maximum of constant-time or O(N) algorithms. Limiting searches/scans as much as possible.
-   - We put particular energy in making sure performances are decent with typical "Debug" build settings as well.
-     Which mean we tend to avoid over-relying on "zero-cost abstraction" as they aren't zero-cost at all.
- - This codebase aims to be both highly opinionated and highly flexible:
-   - This code works because of the things it choose to solve or not solve.
-   - C++: this is a pragmatic C-ish codebase: we don't use fancy C++ features, we don't include C++ headers,
-     and ImGui:: is a namespace. We rarely use member functions (and when we did, I am mostly regretting it now).
-     This is to increase compatibility, increase maintainability and facilitate use from other languages.
-   - C++: ImVec2/ImVec4 do not expose math operators by default, because it is expected that you use your own math types.
-     See FAQ "How can I use my own math types instead of ImVec2/ImVec4?" for details about setting up imconfig.h for that.
-     We can can optionally export math operators for ImVec2/ImVec4 using IMGUI_DEFINE_MATH_OPERATORS, which we use internally.
-   - C++: pay attention that ImVector<> manipulates plain-old-data and does not honor construction/destruction
-     (so don't use ImVector in your code or at our own risk!).
-   - Building: We don't use nor mandate a build system for the main library.
-     This is in an effort to ensure that it works in the real world aka with any esoteric build setup.
-     This is also because providing a build system for the main library would be of little-value.
-     The build problems are almost never coming from the main library but from specific backends.
-
-
- HOW TO UPDATE TO A NEWER VERSION OF DEAR IMGUI
- ----------------------------------------------
- - Update submodule or copy/overwrite every file.
- - About imconfig.h:
-   - You may modify your copy of imconfig.h, in this case don't overwrite it.
-   - or you may locally branch to modify imconfig.h and merge/rebase latest.
-   - or you may '#define IMGUI_USER_CONFIG "my_config_file.h"' globally from your build system to
-     specify a custom path for your imconfig.h file and instead not have to modify the default one.
-
- - Overwrite all the sources files except for imconfig.h (if you have modified your copy of imconfig.h)
- - Or maintain your own branch where you have imconfig.h modified as a top-most commit which you can regularly rebase over "master".
- - You can also use '#define IMGUI_USER_CONFIG "my_config_file.h" to redirect configuration to your own file.
- - Read the "API BREAKING CHANGES" section (below). This is where we list occasional API breaking changes.
-   If a function/type has been renamed / or marked obsolete, try to fix the name in your code before it is permanently removed
-   from the public API. If you have a problem with a missing function/symbols, search for its name in the code, there will
-   likely be a comment about it. Please report any issue to the GitHub page!
- - To find out usage of old API, you can add '#define IMGUI_DISABLE_OBSOLETE_FUNCTIONS' in your configuration file.
- - Try to keep your copy of Dear ImGui reasonably up to date!
-
-
- GETTING STARTED WITH INTEGRATING DEAR IMGUI IN YOUR CODE/ENGINE
- ---------------------------------------------------------------
- - See https://github.com/ocornut/imgui/wiki/Getting-Started.
- - Run and study the examples and demo in imgui_demo.cpp to get acquainted with the library.
- - In the majority of cases you should be able to use unmodified backends files available in the backends/ folder.
- - Add the Dear ImGui source files + selected backend source files to your projects or using your preferred build system.
-   It is recommended you build and statically link the .cpp files as part of your project and NOT as a shared library (DLL).
- - You can later customize the imconfig.h file to tweak some compile-time behavior, such as integrating Dear ImGui types with your own maths types.
- - When using Dear ImGui, your programming IDE is your friend: follow the declaration of variables, functions and types to find comments about them.
- - Dear ImGui never touches or knows about your GPU state. The only function that knows about GPU is the draw function that you provide.
-   Effectively it means you can create widgets at any time in your code, regardless of considerations of being in "update" vs "render"
-   phases of your own application. All rendering information is stored into command-lists that you will retrieve after calling ImGui::Render().
- - Refer to the backends and demo applications in the examples/ folder for instruction on how to setup your code.
- - If you are running over a standard OS with a common graphics API, you should be able to use unmodified imgui_impl_*** files from the examples/ folder.
-
-
- HOW A SIMPLE APPLICATION MAY LOOK LIKE
- --------------------------------------
- EXHIBIT 1: USING THE EXAMPLE BACKENDS (= imgui_impl_XXX.cpp files from the backends/ folder).
- The sub-folders in examples/ contain examples applications following this structure.
-
-     // Application init: create a dear imgui context, setup some options, load fonts
-     ImGui::CreateContext();
-     ImGuiIO& io = ImGui::GetIO();
-     // TODO: Set optional io.ConfigFlags values, e.g. 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard' to enable keyboard controls.
-     // TODO: Fill optional fields of the io structure later.
-     // TODO: Load TTF/OTF fonts if you don't want to use the default font.
-
-     // Initialize helper Platform and Renderer backends (here we are using imgui_impl_win32.cpp and imgui_impl_dx11.cpp)
-     ImGui_ImplWin32_Init(hwnd);
-     ImGui_ImplDX11_Init(g_pd3dDevice, g_pd3dDeviceContext);
-
-     // Application main loop
-     while (true)
-     {
-         // Feed inputs to dear imgui, start new frame
-         ImGui_ImplDX11_NewFrame();
-         ImGui_ImplWin32_NewFrame();
-         ImGui::NewFrame();
-
-         // Any application code here
-         ImGui::Text("Hello, world!");
-
-         // Render dear imgui into screen
-         ImGui::Render();
-         ImGui_ImplDX11_RenderDrawData(ImGui::GetDrawData());
-         g_pSwapChain->Present(1, 0);
-     }
-
-     // Shutdown
-     ImGui_ImplDX11_Shutdown();
-     ImGui_ImplWin32_Shutdown();
-     ImGui::DestroyContext();
-
- EXHIBIT 2: IMPLEMENTING CUSTOM BACKEND / CUSTOM ENGINE
-
-     // Application init: create a dear imgui context, setup some options, load fonts
-     ImGui::CreateContext();
-     ImGuiIO& io = ImGui::GetIO();
-     // TODO: Set optional io.ConfigFlags values, e.g. 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard' to enable keyboard controls.
-     // TODO: Fill optional fields of the io structure later.
-     // TODO: Load TTF/OTF fonts if you don't want to use the default font.
-
-     // Build and load the texture atlas into a texture
-     // (In the examples/ app this is usually done within the ImGui_ImplXXX_Init() function from one of the demo Renderer)
-     int width, height;
-     unsigned char* pixels = nullptr;
-     io.Fonts->GetTexDataAsRGBA32(&pixels, &width, &height);
-
-     // At this point you've got the texture data and you need to upload that to your graphic system:
-     // After we have created the texture, store its pointer/identifier (_in whichever format your engine uses_) in 'io.Fonts->TexID'.
-     // This will be passed back to your via the renderer. Basically ImTextureID == void*. Read FAQ for details about ImTextureID.
-     MyTexture* texture = MyEngine::CreateTextureFromMemoryPixels(pixels, width, height, TEXTURE_TYPE_RGBA32)
-     io.Fonts->SetTexID((void*)texture);
-
-     // Application main loop
-     while (true)
-     {
-        // Setup low-level inputs, e.g. on Win32: calling GetKeyboardState(), or write to those fields from your Windows message handlers, etc.
-        // (In the examples/ app this is usually done within the ImGui_ImplXXX_NewFrame() function from one of the demo Platform Backends)
-        io.DeltaTime = 1.0f/60.0f;              // set the time elapsed since the previous frame (in seconds)
-        io.DisplaySize.x = 1920.0f;             // set the current display width
-        io.DisplaySize.y = 1280.0f;             // set the current display height here
-        io.AddMousePosEvent(mouse_x, mouse_y);  // update mouse position
-        io.AddMouseButtonEvent(0, mouse_b[0]);  // update mouse button states
-        io.AddMouseButtonEvent(1, mouse_b[1]);  // update mouse button states
-
-        // Call NewFrame(), after this point you can use ImGui::* functions anytime
-        // (So you want to try calling NewFrame() as early as you can in your main loop to be able to use Dear ImGui everywhere)
-        ImGui::NewFrame();
-
-        // Most of your application code here
-        ImGui::Text("Hello, world!");
-        MyGameUpdate(); // may use any Dear ImGui functions, e.g. ImGui::Begin("My window"); ImGui::Text("Hello, world!"); ImGui::End();
-        MyGameRender(); // may use any Dear ImGui functions as well!
-
-        // Render dear imgui, swap buffers
-        // (You want to try calling EndFrame/Render as late as you can, to be able to use Dear ImGui in your own game rendering code)
-        ImGui::EndFrame();
-        ImGui::Render();
-        ImDrawData* draw_data = ImGui::GetDrawData();
-        MyImGuiRenderFunction(draw_data);
-        SwapBuffers();
-     }
-
-     // Shutdown
-     ImGui::DestroyContext();
-
- To decide whether to dispatch mouse/keyboard inputs to Dear ImGui to the rest of your application,
- you should read the 'io.WantCaptureMouse', 'io.WantCaptureKeyboard' and 'io.WantTextInput' flags!
- Please read the FAQ entry "How can I tell whether to dispatch mouse/keyboard to Dear ImGui or my application?" about this.
-
-
- HOW A SIMPLE RENDERING FUNCTION MAY LOOK LIKE
- ---------------------------------------------
- The backends in impl_impl_XXX.cpp files contain many working implementations of a rendering function.
-
-    void MyImGuiRenderFunction(ImDrawData* draw_data)
-    {
-       // TODO: Setup render state: alpha-blending enabled, no face culling, no depth testing, scissor enabled
-       // TODO: Setup texture sampling state: sample with bilinear filtering (NOT point/nearest filtering). Use 'io.Fonts->Flags |= ImFontAtlasFlags_NoBakedLines;' to allow point/nearest filtering.
-       // TODO: Setup viewport covering draw_data->DisplayPos to draw_data->DisplayPos + draw_data->DisplaySize
-       // TODO: Setup orthographic projection matrix cover draw_data->DisplayPos to draw_data->DisplayPos + draw_data->DisplaySize
-       // TODO: Setup shader: vertex { float2 pos, float2 uv, u32 color }, fragment shader sample color from 1 texture, multiply by vertex color.
-       ImVec2 clip_off = draw_data->DisplayPos;
-       for (int n = 0; n < draw_data->CmdListsCount; n++)
-       {
-          const ImDrawList* cmd_list = draw_data->CmdLists[n];
-          const ImDrawVert* vtx_buffer = cmd_list->VtxBuffer.Data;  // vertex buffer generated by Dear ImGui
-          const ImDrawIdx* idx_buffer = cmd_list->IdxBuffer.Data;   // index buffer generated by Dear ImGui
-          for (int cmd_i = 0; cmd_i < cmd_list->CmdBuffer.Size; cmd_i++)
-          {
-             const ImDrawCmd* pcmd = &cmd_list->CmdBuffer[cmd_i];
-             if (pcmd->UserCallback)
-             {
-                 pcmd->UserCallback(cmd_list, pcmd);
-             }
-             else
-             {
-                 // Project scissor/clipping rectangles into framebuffer space
-                 ImVec2 clip_min(pcmd->ClipRect.x - clip_off.x, pcmd->ClipRect.y - clip_off.y);
-                 ImVec2 clip_max(pcmd->ClipRect.z - clip_off.x, pcmd->ClipRect.w - clip_off.y);
-                 if (clip_max.x <= clip_min.x || clip_max.y <= clip_min.y)
-                     continue;
-
-                 // We are using scissoring to clip some objects. All low-level graphics API should support it.
-                 // - If your engine doesn't support scissoring yet, you may ignore this at first. You will get some small glitches
-                 //   (some elements visible outside their bounds) but you can fix that once everything else works!
-                 // - Clipping coordinates are provided in imgui coordinates space:
-                 //   - For a given viewport, draw_data->DisplayPos == viewport->Pos and draw_data->DisplaySize == viewport->Size
-                 //   - In a single viewport application, draw_data->DisplayPos == (0,0) and draw_data->DisplaySize == io.DisplaySize, but always use GetMainViewport()->Pos/Size instead of hardcoding those values.
-                 //   - In the interest of supporting multi-viewport applications (see 'docking' branch on github),
-                 //     always subtract draw_data->DisplayPos from clipping bounds to convert them to your viewport space.
-                 // - Note that pcmd->ClipRect contains Min+Max bounds. Some graphics API may use Min+Max, other may use Min+Size (size being Max-Min)
-                 MyEngineSetScissor(clip_min.x, clip_min.y, clip_max.x, clip_max.y);
-
-                 // The texture for the draw call is specified by pcmd->GetTexID().
-                 // The vast majority of draw calls will use the Dear ImGui texture atlas, which value you have set yourself during initialization.
-                 MyEngineBindTexture((MyTexture*)pcmd->GetTexID());
-
-                 // Render 'pcmd->ElemCount/3' indexed triangles.
-                 // By default the indices ImDrawIdx are 16-bit, you can change them to 32-bit in imconfig.h if your engine doesn't support 16-bit indices.
-                 MyEngineDrawIndexedTriangles(pcmd->ElemCount, sizeof(ImDrawIdx) == 2 ? GL_UNSIGNED_SHORT : GL_UNSIGNED_INT, idx_buffer + pcmd->IdxOffset, vtx_buffer, pcmd->VtxOffset);
-             }
-          }
-       }
-    }

- API BREAKING CHANGES
- ====================
-
- Occasionally introducing changes that are breaking the API. We try to make the breakage minor and easy to fix.
- Below is a change-log of API breaking changes only. If you are using one of the functions listed, expect to have to fix some code.
- When you are not sure about an old symbol or function name, try using the Search/Find function of your IDE to look for comments or references in all imgui files.
- You can read releases logs https://github.com/ocornut/imgui/releases for more details.
-
- - 2024/01/15 (1.90.2) - commented out obsolete ImGuiIO::ImeWindowHandle marked obsolete in 1.87, favor of writing to 'void* ImGuiViewport::PlatformHandleRaw'.
- - 2023/12/19 (1.90.1) - commented out obsolete ImGuiKey_KeyPadEnter redirection to ImGuiKey_KeypadEnter.
- - 2023/11/06 (1.90.1) - removed CalcListClipping() marked obsolete in 1.86. Prefer using ImGuiListClipper which can return non-contiguous ranges.
- - 2023/11/05 (1.90.1) - imgui_freetype: commented out ImGuiFreeType::BuildFontAtlas() obsoleted in 1.81. prefer using #define IMGUI_ENABLE_FREETYPE or see commented code for manual calls.
- - 2023/11/05 (1.90.1) - internals,columns: commented out legacy ImGuiColumnsFlags_XXX symbols redirecting to ImGuiOldColumnsFlags_XXX, obsoleted from imgui_internal.h in 1.80.
- - 2023/11/09 (1.90.0) - removed IM_OFFSETOF() macro in favor of using offsetof() available in C++11. Kept redirection define (will obsolete).
- - 2023/11/07 (1.90.0) - removed BeginChildFrame()/EndChildFrame() in favor of using BeginChild() with the ImGuiChildFlags_FrameStyle flag. kept inline redirection function (will obsolete).
-                         those functions were merely PushStyle/PopStyle helpers, the removal isn't so much motivated by needing to add the feature in BeginChild(), but by the necessity to avoid BeginChildFrame() signature mismatching BeginChild() signature and features.
- - 2023/11/02 (1.90.0) - BeginChild: upgraded 'bool border = true' parameter to 'ImGuiChildFlags flags' type, added ImGuiChildFlags_Border equivalent. As with our prior "bool-to-flags" API updates, the ImGuiChildFlags_Border value is guaranteed to be == true forever to ensure a smoother transition, meaning all existing calls will still work.
-                           - old: BeginChild("Name", size, true)
-                           - new: BeginChild("Name", size, ImGuiChildFlags_Border)
-                           - old: BeginChild("Name", size, false)
-                           - new: BeginChild("Name", size) or BeginChild("Name", 0) or BeginChild("Name", size, ImGuiChildFlags_None)
- - 2023/11/02 (1.90.0) - BeginChild: added child-flag ImGuiChildFlags_AlwaysUseWindowPadding as a replacement for the window-flag ImGuiWindowFlags_AlwaysUseWindowPadding: the feature only ever made sense for BeginChild() anyhow.
-                           - old: BeginChild("Name", size, 0, ImGuiWindowFlags_AlwaysUseWindowPadding);
-                           - new: BeginChild("Name", size, ImGuiChildFlags_AlwaysUseWindowPadding, 0);
- - 2023/09/27 (1.90.0) - io: removed io.MetricsActiveAllocations introduced in 1.63. Same as 'g.DebugMemAllocCount - g.DebugMemFreeCount' (still displayed in Metrics, unlikely to be accessed by end-user).
- - 2023/09/26 (1.90.0) - debug tools: Renamed ShowStackToolWindow() ("Stack Tool") to ShowIDStackToolWindow() ("ID Stack Tool"), as earlier name was misleading. Kept inline redirection function. (#4631)
- - 2023/09/15 (1.90.0) - ListBox, Combo: changed signature of "name getter" callback in old one-liner ListBox()/Combo() apis. kept inline redirection function (will obsolete).
-                           - old: bool Combo(const char* label, int* current_item, bool (*getter)(void* user_data, int idx, const char** out_text), ...)
-                           - new: bool Combo(const char* label, int* current_item, const char* (*getter)(void* user_data, int idx), ...);
-                           - old: bool ListBox(const char* label, int* current_item, bool (*getting)(void* user_data, int idx, const char** out_text), ...);
-                           - new: bool ListBox(const char* label, int* current_item, const char* (*getter)(void* user_data, int idx), ...);
- - 2023/09/08 (1.90.0) - commented out obsolete redirecting functions:
-                           - GetWindowContentRegionWidth()  -> use GetWindowContentRegionMax().x - GetWindowContentRegionMin().x. Consider that generally 'GetContentRegionAvail().x' is more useful.
-                           - ImDrawCornerFlags_XXX          -> use ImDrawFlags_RoundCornersXXX flags. Read 1.82 Changelog for details + grep commented names in sources.
-                       - commented out runtime support for hardcoded ~0 or 0x01..0x0F rounding flags values for AddRect()/AddRectFilled()/PathRect()/AddImageRounded() -> use ImDrawFlags_RoundCornersXXX flags. Read 1.82 Changelog for details
- - 2023/08/25 (1.89.9) - clipper: Renamed IncludeRangeByIndices() (also called ForceDisplayRangeByIndices() before 1.89.6) to IncludeItemsByIndex(). Kept inline redirection function. Sorry!
- - 2023/07/12 (1.89.8) - ImDrawData: CmdLists now owned, changed from ImDrawList** to ImVector<ImDrawList*>. Majority of users shouldn't be affected, but you cannot compare to NULL nor reassign manually anymore. Instead use AddDrawList(). (#6406, #4879, #1878)
- - 2023/06/28 (1.89.7) - overlapping items: obsoleted 'SetItemAllowOverlap()' (called after item) in favor of calling 'SetNextItemAllowOverlap()' (called before item). 'SetItemAllowOverlap()' didn't and couldn't work reliably since 1.89 (2022-11-15).
- - 2023/06/28 (1.89.7) - overlapping items: renamed 'ImGuiTreeNodeFlags_AllowItemOverlap' to 'ImGuiTreeNodeFlags_AllowOverlap', 'ImGuiSelectableFlags_AllowItemOverlap' to 'ImGuiSelectableFlags_AllowOverlap'. Kept redirecting enums (will obsolete).
- - 2023/06/28 (1.89.7) - overlapping items: IsItemHovered() now by default return false when querying an item using AllowOverlap mode which is being overlapped. Use ImGuiHoveredFlags_AllowWhenOverlappedByItem to revert to old behavior.
- - 2023/06/28 (1.89.7) - overlapping items: Selectable and TreeNode don't allow overlap when active so overlapping widgets won't appear as hovered. While this fixes a common small visual issue, it also means that calling IsItemHovered() after a non-reactive elements - e.g. Text() - overlapping an active one may fail if you don't use IsItemHovered(ImGuiHoveredFlags_AllowWhenBlockedByActiveItem). (#6610)
- - 2023/06/20 (1.89.7) - moved io.HoverDelayShort/io.HoverDelayNormal to style.HoverDelayShort/style.HoverDelayNormal. As the fields were added in 1.89 and expected to be left unchanged by most users, or only tweaked once during app initialization, we are exceptionally accepting the breakage.
- - 2023/05/30 (1.89.6) - backends: renamed "imgui_impl_sdlrenderer.cpp" to "imgui_impl_sdlrenderer2.cpp" and "imgui_impl_sdlrenderer.h" to "imgui_impl_sdlrenderer2.h". This is in prevision for the future release of SDL3.
- - 2023/05/22 (1.89.6) - listbox: commented out obsolete/redirecting functions that were marked obsolete more than two years ago:
-                           - ListBoxHeader()  -> use BeginListBox() (note how two variants of ListBoxHeader() existed. Check commented versions in imgui.h for reference)
-                           - ListBoxFooter()  -> use EndListBox()
- - 2023/05/15 (1.89.6) - clipper: commented out obsolete redirection constructor 'ImGuiListClipper(int items_count, float items_height = -1.0f)' that was marked obsolete in 1.79. Use default constructor + clipper.Begin().
- - 2023/05/15 (1.89.6) - clipper: renamed ImGuiListClipper::ForceDisplayRangeByIndices() to ImGuiListClipper::IncludeRangeByIndices().
- - 2023/03/14 (1.89.4) - commented out redirecting enums/functions names that were marked obsolete two years ago:
-                           - ImGuiSliderFlags_ClampOnInput        -> use ImGuiSliderFlags_AlwaysClamp
-                           - ImGuiInputTextFlags_AlwaysInsertMode -> use ImGuiInputTextFlags_AlwaysOverwrite
-                           - ImDrawList::AddBezierCurve()         -> use ImDrawList::AddBezierCubic()
-                           - ImDrawList::PathBezierCurveTo()      -> use ImDrawList::PathBezierCubicCurveTo()
- - 2023/03/09 (1.89.4) - renamed PushAllowKeyboardFocus()/PopAllowKeyboardFocus() to PushTabStop()/PopTabStop(). Kept inline redirection functions (will obsolete).
- - 2023/03/09 (1.89.4) - tooltips: Added 'bool' return value to BeginTooltip() for API consistency. Please only submit contents and call EndTooltip() if BeginTooltip() returns true. In reality the function will _currently_ always return true, but further changes down the line may change this, best to clarify API sooner.
- - 2023/02/15 (1.89.4) - moved the optional "courtesy maths operators" implementation from imgui_internal.h in imgui.h.
-                         Even though we encourage using your own maths types and operators by setting up IM_VEC2_CLASS_EXTRA,
-                         it has been frequently requested by people to use our own. We had an opt-in define which was
-                         previously fulfilled in imgui_internal.h. It is now fulfilled in imgui.h. (#6164)
-                           - OK:     #define IMGUI_DEFINE_MATH_OPERATORS / #include "imgui.h" / #include "imgui_internal.h"
-                           - Error:  #include "imgui.h" / #define IMGUI_DEFINE_MATH_OPERATORS / #include "imgui_internal.h"
- - 2023/02/07 (1.89.3) - backends: renamed "imgui_impl_sdl.cpp" to "imgui_impl_sdl2.cpp" and "imgui_impl_sdl.h" to "imgui_impl_sdl2.h". (#6146) This is in prevision for the future release of SDL3.
- - 2022/10/26 (1.89)   - commented out redirecting OpenPopupContextItem() which was briefly the name of OpenPopupOnItemClick() from 1.77 to 1.79.
- - 2022/10/12 (1.89)   - removed runtime patching of invalid "%f"/"%0.f" format strings for DragInt()/SliderInt(). This was obsoleted in 1.61 (May 2018). See 1.61 changelog for details.
- - 2022/09/26 (1.89)   - renamed and merged keyboard modifiers key enums and flags into a same set. Kept inline redirection enums (will obsolete).
-                           - ImGuiKey_ModCtrl  and ImGuiModFlags_Ctrl  -> ImGuiMod_Ctrl
-                           - ImGuiKey_ModShift and ImGuiModFlags_Shift -> ImGuiMod_Shift
-                           - ImGuiKey_ModAlt   and ImGuiModFlags_Alt   -> ImGuiMod_Alt
-                           - ImGuiKey_ModSuper and ImGuiModFlags_Super -> ImGuiMod_Super
-                         the ImGuiKey_ModXXX were introduced in 1.87 and mostly used by backends.
-                         the ImGuiModFlags_XXX have been exposed in imgui.h but not really used by any public api only by third-party extensions.
-                         exceptionally commenting out the older ImGuiKeyModFlags_XXX names ahead of obsolescence schedule to reduce confusion and because they were not meant to be used anyway.
- - 2022/09/20 (1.89)   - ImGuiKey is now a typed enum, allowing ImGuiKey_XXX symbols to be named in debuggers.
-                         this will require uses of legacy backend-dependent indices to be casted, e.g.
-                            - with imgui_impl_glfw:  IsKeyPressed(GLFW_KEY_A) -> IsKeyPressed((ImGuiKey)GLFW_KEY_A);
-                            - with imgui_impl_win32: IsKeyPressed('A')        -> IsKeyPressed((ImGuiKey)'A')
-                            - etc. However if you are upgrading code you might well use the better, backend-agnostic IsKeyPressed(ImGuiKey_A) now!
- - 2022/09/12 (1.89) - removed the bizarre legacy default argument for 'TreePush(const void* ptr = NULL)', always pass a pointer value explicitly. NULL/nullptr is ok but require cast, e.g. TreePush((void*)nullptr);
- - 2022/09/05 (1.89) - commented out redirecting functions/enums names that were marked obsolete in 1.77 and 1.78 (June 2020):
-                         - DragScalar(), DragScalarN(), DragFloat(), DragFloat2(), DragFloat3(), DragFloat4(): For old signatures ending with (..., const char* format, float power = 1.0f) -> use (..., format ImGuiSliderFlags_Logarithmic) if power != 1.0f.
-                         - SliderScalar(), SliderScalarN(), SliderFloat(), SliderFloat2(), SliderFloat3(), SliderFloat4(): For old signatures ending with (..., const char* format, float power = 1.0f) -> use (..., format ImGuiSliderFlags_Logarithmic) if power != 1.0f.
-                         - BeginPopupContextWindow(const char*, ImGuiMouseButton, bool) -> use BeginPopupContextWindow(const char*, ImGuiPopupFlags)
- - 2022/09/02 (1.89) - obsoleted using SetCursorPos()/SetCursorScreenPos() to extend parent window/cell boundaries.
-                       this relates to when moving the cursor position beyond current boundaries WITHOUT submitting an item.
-                         - previously this would make the window content size ~200x200:
-                              Begin(...) + SetCursorScreenPos(GetCursorScreenPos() + ImVec2(200,200)) + End();
-                         - instead, please submit an item:
-                              Begin(...) + SetCursorScreenPos(GetCursorScreenPos() + ImVec2(200,200)) + Dummy(ImVec2(0,0)) + End();
-                         - alternative:
-                              Begin(...) + Dummy(ImVec2(200,200)) + End();
-                         - content size is now only extended when submitting an item!
-                         - with '#define IMGUI_DISABLE_OBSOLETE_FUNCTIONS' this will now be detected and assert.
-                         - without '#define IMGUI_DISABLE_OBSOLETE_FUNCTIONS' this will silently be fixed until we obsolete it.
- - 2022/08/03 (1.89) - changed signature of ImageButton() function. Kept redirection function (will obsolete).
-                        - added 'const char* str_id' parameter + removed 'int frame_padding = -1' parameter.
-                        - old signature: bool ImageButton(ImTextureID tex_id, ImVec2 size, ImVec2 uv0 = ImVec2(0,0), ImVec2 uv1 = ImVec2(1,1), int frame_padding = -1, ImVec4 bg_col = ImVec4(0,0,0,0), ImVec4 tint_col = ImVec4(1,1,1,1));
-                          - used the ImTextureID value to create an ID. This was inconsistent with other functions, led to ID conflicts, and caused problems with engines using transient ImTextureID values.
-                          - had a FramePadding override which was inconsistent with other functions and made the already-long signature even longer.
-                        - new signature: bool ImageButton(const char* str_id, ImTextureID tex_id, ImVec2 size, ImVec2 uv0 = ImVec2(0,0), ImVec2 uv1 = ImVec2(1,1), ImVec4 bg_col = ImVec4(0,0,0,0), ImVec4 tint_col = ImVec4(1,1,1,1));
-                          - requires an explicit identifier. You may still use e.g. PushID() calls and then pass an empty identifier.
-                          - always uses style.FramePadding for padding, to be consistent with other buttons. You may use PushStyleVar() to alter this.
- - 2022/07/08 (1.89) - inputs: removed io.NavInputs[] and ImGuiNavInput enum (following 1.87 changes).
-                        - Official backends from 1.87+                  -> no issue.
-                        - Official backends from 1.60 to 1.86           -> will build and convert gamepad inputs, unless IMGUI_DISABLE_OBSOLETE_KEYIO is defined. Need updating!
-                        - Custom backends not writing to io.NavInputs[] -> no issue.
-                        - Custom backends writing to io.NavInputs[]     -> will build and convert gamepad inputs, unless IMGUI_DISABLE_OBSOLETE_KEYIO is defined. Need fixing!
-                        - TL;DR: Backends should call io.AddKeyEvent()/io.AddKeyAnalogEvent() with ImGuiKey_GamepadXXX values instead of filling io.NavInput[].
- - 2022/06/15 (1.88) - renamed IMGUI_DISABLE_METRICS_WINDOW to IMGUI_DISABLE_DEBUG_TOOLS for correctness. kept support for old define (will obsolete).
- - 2022/05/03 (1.88) - backends: osx: removed ImGui_ImplOSX_HandleEvent() from backend API in favor of backend automatically handling event capture. All ImGui_ImplOSX_HandleEvent() calls should be removed as they are now unnecessary.
- - 2022/04/05 (1.88) - inputs: renamed ImGuiKeyModFlags to ImGuiModFlags. Kept inline redirection enums (will obsolete). This was never used in public API functions but technically present in imgui.h and ImGuiIO.
- - 2022/01/20 (1.87) - inputs: reworded gamepad IO.
-                        - Backend writing to io.NavInputs[]            -> backend should call io.AddKeyEvent()/io.AddKeyAnalogEvent() with ImGuiKey_GamepadXXX values.
- - 2022/01/19 (1.87) - sliders, drags: removed support for legacy arithmetic operators (+,+-,*,/) when inputing text. This doesn't break any api/code but a feature that used to be accessible by end-users (which seemingly no one used).
- - 2022/01/17 (1.87) - inputs: reworked mouse IO.
-                        - Backend writing to io.MousePos               -> backend should call io.AddMousePosEvent()
-                        - Backend writing to io.MouseDown[]            -> backend should call io.AddMouseButtonEvent()
-                        - Backend writing to io.MouseWheel             -> backend should call io.AddMouseWheelEvent()
-                        - Backend writing to io.MouseHoveredViewport   -> backend should call io.AddMouseViewportEvent() [Docking branch w/ multi-viewports only]
-                       note: for all calls to IO new functions, the Dear ImGui context should be bound/current.
-                       read https://github.com/ocornut/imgui/issues/4921 for details.
- - 2022/01/10 (1.87) - inputs: reworked keyboard IO. Removed io.KeyMap[], io.KeysDown[] in favor of calling io.AddKeyEvent(). Removed GetKeyIndex(), now unecessary. All IsKeyXXX() functions now take ImGuiKey values. All features are still functional until IMGUI_DISABLE_OBSOLETE_KEYIO is defined. Read Changelog and Release Notes for details.
-                        - IsKeyPressed(MY_NATIVE_KEY_XXX)              -> use IsKeyPressed(ImGuiKey_XXX)
-                        - IsKeyPressed(GetKeyIndex(ImGuiKey_XXX))      -> use IsKeyPressed(ImGuiKey_XXX)
-                        - Backend writing to io.KeyMap[],io.KeysDown[] -> backend should call io.AddKeyEvent() (+ call io.SetKeyEventNativeData() if you want legacy user code to stil function with legacy key codes).
-                        - Backend writing to io.KeyCtrl, io.KeyShift.. -> backend should call io.AddKeyEvent() with ImGuiMod_XXX values. *IF YOU PULLED CODE BETWEEN 2021/01/10 and 2021/01/27: We used to have a io.AddKeyModsEvent() function which was now replaced by io.AddKeyEvent() with ImGuiMod_XXX values.*
-                     - one case won't work with backward compatibility: if your custom backend used ImGuiKey as mock native indices (e.g. "io.KeyMap[ImGuiKey_A] = ImGuiKey_A") because those values are now larger than the legacy KeyDown[] array. Will assert.
-                     - inputs: added ImGuiKey_ModCtrl/ImGuiKey_ModShift/ImGuiKey_ModAlt/ImGuiKey_ModSuper values to submit keyboard modifiers using io.AddKeyEvent(), instead of writing directly to io.KeyCtrl, io.KeyShift, io.KeyAlt, io.KeySuper.
- - 2022/01/05 (1.87) - inputs: renamed ImGuiKey_KeyPadEnter to ImGuiKey_KeypadEnter to align with new symbols. Kept redirection enum.
- - 2022/01/05 (1.87) - removed io.ImeSetInputScreenPosFn() in favor of more flexible io.SetPlatformImeDataFn(). Removed 'void* io.ImeWindowHandle' in favor of writing to 'void* ImGuiViewport::PlatformHandleRaw'.
- - 2022/01/01 (1.87) - commented out redirecting functions/enums names that were marked obsolete in 1.69, 1.70, 1.71, 1.72 (March-July 2019)
-                        - ImGui::SetNextTreeNodeOpen()        -> use ImGui::SetNextItemOpen()
-                        - ImGui::GetContentRegionAvailWidth() -> use ImGui::GetContentRegionAvail().x
-                        - ImGui::TreeAdvanceToLabelPos()      -> use ImGui::SetCursorPosX(ImGui::GetCursorPosX() + ImGui::GetTreeNodeToLabelSpacing());
-                        - ImFontAtlas::CustomRect             -> use ImFontAtlasCustomRect
-                        - ImGuiColorEditFlags_RGB/HSV/HEX     -> use ImGuiColorEditFlags_DisplayRGB/HSV/Hex
- - 2021/12/20 (1.86) - backends: removed obsolete Marmalade backend (imgui_impl_marmalade.cpp) + example. Find last supported version at https://github.com/ocornut/imgui/wiki/Bindings
- - 2021/11/04 (1.86) - removed CalcListClipping() function. Prefer using ImGuiListClipper which can return non-contiguous ranges. Please open an issue if you think you really need this function.
- - 2021/08/23 (1.85) - removed GetWindowContentRegionWidth() function. keep inline redirection helper. can use 'GetWindowContentRegionMax().x - GetWindowContentRegionMin().x' instead for generally 'GetContentRegionAvail().x' is more useful.
- - 2021/07/26 (1.84) - commented out redirecting functions/enums names that were marked obsolete in 1.67 and 1.69 (March 2019):
-                        - ImGui::GetOverlayDrawList() -> use ImGui::GetForegroundDrawList()
-                        - ImFont::GlyphRangesBuilder  -> use ImFontGlyphRangesBuilder
- - 2021/05/19 (1.83) - backends: obsoleted direct access to ImDrawCmd::TextureId in favor of calling ImDrawCmd::GetTexID().
-                        - if you are using official backends from the source tree: you have nothing to do.
-                        - if you have copied old backend code or using your own: change access to draw_cmd->TextureId to draw_cmd->GetTexID().
- - 2021/03/12 (1.82) - upgraded ImDrawList::AddRect(), AddRectFilled(), PathRect() to use ImDrawFlags instead of ImDrawCornersFlags.
-                        - ImDrawCornerFlags_TopLeft  -> use ImDrawFlags_RoundCornersTopLeft
-                        - ImDrawCornerFlags_BotRight -> use ImDrawFlags_RoundCornersBottomRight
-                        - ImDrawCornerFlags_None     -> use ImDrawFlags_RoundCornersNone etc.
-                       flags now sanely defaults to 0 instead of 0x0F, consistent with all other flags in the API.
-                       breaking: the default with rounding > 0.0f is now "round all corners" vs old implicit "round no corners":
-                        - rounding == 0.0f + flags == 0 --> meant no rounding  --> unchanged (common use)
-                        - rounding  > 0.0f + flags != 0 --> meant rounding     --> unchanged (common use)
-                        - rounding == 0.0f + flags != 0 --> meant no rounding  --> unchanged (unlikely use)
-                        - rounding  > 0.0f + flags == 0 --> meant no rounding  --> BREAKING (unlikely use): will now round all corners --> use ImDrawFlags_RoundCornersNone or rounding == 0.0f.
-                       this ONLY matters for hard coded use of 0 + rounding > 0.0f. Use of named ImDrawFlags_RoundCornersNone (new) or ImDrawCornerFlags_None (old) are ok.
-                       the old ImDrawCornersFlags used awkward default values of ~0 or 0xF (4 lower bits set) to signify "round all corners" and we sometimes encouraged using them as shortcuts.
-                       legacy path still support use of hard coded ~0 or any value from 0x1 or 0xF. They will behave the same with legacy paths enabled (will assert otherwise).
- - 2021/03/11 (1.82) - removed redirecting functions/enums names that were marked obsolete in 1.66 (September 2018):
-                        - ImGui::SetScrollHere()              -> use ImGui::SetScrollHereY()
- - 2021/03/11 (1.82) - clarified that ImDrawList::PathArcTo(), ImDrawList::PathArcToFast() won't render with radius < 0.0f. Previously it sorts of accidentally worked but would generally lead to counter-clockwise paths and have an effect on anti-aliasing.
- - 2021/03/10 (1.82) - upgraded ImDrawList::AddPolyline() and PathStroke() "bool closed" parameter to "ImDrawFlags flags". The matching ImDrawFlags_Closed value is guaranteed to always stay == 1 in the future.
- - 2021/02/22 (1.82) - (*undone in 1.84*) win32+mingw: Re-enabled IME functions by default even under MinGW. In July 2016, issue #738 had me incorrectly disable those default functions for MinGW. MinGW users should: either link with -limm32, either set their imconfig file  with '#define IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCTIONS'.
- - 2021/02/17 (1.82) - renamed rarely used style.CircleSegmentMaxError (old default = 1.60f) to style.CircleTessellationMaxError (new default = 0.30f) as the meaning of the value changed.
- - 2021/02/03 (1.81) - renamed ListBoxHeader(const char* label, ImVec2 size) to BeginListBox(). Kept inline redirection function (will obsolete).
-                     - removed ListBoxHeader(const char* label, int items_count, int height_in_items = -1) in favor of specifying size. Kept inline redirection function (will obsolete).
-                     - renamed ListBoxFooter() to EndListBox(). Kept inline redirection function (will obsolete).
- - 2021/01/26 (1.81) - removed ImGuiFreeType::BuildFontAtlas(). Kept inline redirection function. Prefer using '#define IMGUI_ENABLE_FREETYPE', but there's a runtime selection path available too. The shared extra flags parameters (very rarely used) are now stored in ImFontAtlas::FontBuilderFlags.
-                     - renamed ImFontConfig::RasterizerFlags (used by FreeType) to ImFontConfig::FontBuilderFlags.
-                     - renamed ImGuiFreeType::XXX flags to ImGuiFreeTypeBuilderFlags_XXX for consistency with other API.
- - 2020/10/12 (1.80) - removed redirecting functions/enums that were marked obsolete in 1.63 (August 2018):
-                        - ImGui::IsItemDeactivatedAfterChange() -> use ImGui::IsItemDeactivatedAfterEdit().
-                        - ImGuiCol_ModalWindowDarkening       -> use ImGuiCol_ModalWindowDimBg
-                        - ImGuiInputTextCallback              -> use ImGuiTextEditCallback
-                        - ImGuiInputTextCallbackData          -> use ImGuiTextEditCallbackData
- - 2020/12/21 (1.80) - renamed ImDrawList::AddBezierCurve() to AddBezierCubic(), and PathBezierCurveTo() to PathBezierCubicCurveTo(). Kept inline redirection function (will obsolete).
- - 2020/12/04 (1.80) - added imgui_tables.cpp file! Manually constructed project files will need the new file added!
- - 2020/11/18 (1.80) - renamed undocumented/internals ImGuiColumnsFlags_* to ImGuiOldColumnFlags_* in prevision of incoming Tables API.
- - 2020/11/03 (1.80) - renamed io.ConfigWindowsMemoryCompactTimer to io.ConfigMemoryCompactTimer as the feature will apply to other data structures
- - 2020/10/14 (1.80) - backends: moved all backends files (imgui_impl_XXXX.cpp, imgui_impl_XXXX.h) from examples/ to backends/.
- - 2020/10/12 (1.80) - removed redirecting functions/enums that were marked obsolete in 1.60 (April 2018):
-                        - io.RenderDrawListsFn pointer        -> use ImGui::GetDrawData() value and call the render function of your backend
-                        - ImGui::IsAnyWindowFocused()         -> use ImGui::IsWindowFocused(ImGuiFocusedFlags_AnyWindow)
-                        - ImGui::IsAnyWindowHovered()         -> use ImGui::IsWindowHovered(ImGuiHoveredFlags_AnyWindow)
-                        - ImGuiStyleVar_Count_                -> use ImGuiStyleVar_COUNT
-                        - ImGuiMouseCursor_Count_             -> use ImGuiMouseCursor_COUNT
-                      - removed redirecting functions names that were marked obsolete in 1.61 (May 2018):
-                        - InputFloat (... int decimal_precision ...) -> use InputFloat (... const char* format ...) with format = "%.Xf" where X is your value for decimal_precision.
-                        - same for InputFloat2()/InputFloat3()/InputFloat4() variants taking a `int decimal_precision` parameter.
- - 2020/10/05 (1.79) - removed ImGuiListClipper: Renamed constructor parameters which created an ambiguous alternative to using the ImGuiListClipper::Begin() function, with misleading edge cases (note: imgui_memory_editor <0.40 from imgui_club/ used this old clipper API. Update your copy if needed).
- - 2020/09/25 (1.79) - renamed ImGuiSliderFlags_ClampOnInput to ImGuiSliderFlags_AlwaysClamp. Kept redirection enum (will obsolete sooner because previous name was added recently).
- - 2020/09/25 (1.79) - renamed style.TabMinWidthForUnselectedCloseButton to style.TabMinWidthForCloseButton.
- - 2020/09/21 (1.79) - renamed OpenPopupContextItem() back to OpenPopupOnItemClick(), reverting the change from 1.77. For varieties of reason this is more self-explanatory.
- - 2020/09/21 (1.79) - removed return value from OpenPopupOnItemClick() - returned true on mouse release on an item - because it is inconsistent with other popup APIs and makes others misleading. It's also and unnecessary: you can use IsWindowAppearing() after BeginPopup() for a similar result.
- - 2020/09/17 (1.79) - removed ImFont::DisplayOffset in favor of ImFontConfig::GlyphOffset. DisplayOffset was applied after scaling and not very meaningful/useful outside of being needed by the default ProggyClean font. If you scaled this value after calling AddFontDefault(), this is now done automatically. It was also getting in the way of better font scaling, so let's get rid of it now!
- - 2020/08/17 (1.78) - obsoleted use of the trailing 'float power=1.0f' parameter for DragFloat(), DragFloat2(), DragFloat3(), DragFloat4(), DragFloatRange2(), DragScalar(), DragScalarN(), SliderFloat(), SliderFloat2(), SliderFloat3(), SliderFloat4(), SliderScalar(), SliderScalarN(), VSliderFloat() and VSliderScalar().
-                       replaced the 'float power=1.0f' argument with integer-based flags defaulting to 0 (as with all our flags).
-                       worked out a backward-compatibility scheme so hopefully most C++ codebase should not be affected. in short, when calling those functions:
-                       - if you omitted the 'power' parameter (likely!), you are not affected.
-                       - if you set the 'power' parameter to 1.0f (same as previous default value): 1/ your compiler may warn on float>int conversion, 2/ everything else will work. 3/ you can replace the 1.0f value with 0 to fix the warning, and be technically correct.
-                       - if you set the 'power' parameter to >1.0f (to enable non-linear editing): 1/ your compiler may warn on float>int conversion, 2/ code will assert at runtime, 3/ in case asserts are disabled, the code will not crash and enable the _Logarithmic flag. 4/ you can replace the >1.0f value with ImGuiSliderFlags_Logarithmic to fix the warning/assert and get a _similar_ effect as previous uses of power >1.0f.
-                       see https://github.com/ocornut/imgui/issues/3361 for all details.
-                       kept inline redirection functions (will obsolete) apart for: DragFloatRange2(), VSliderFloat(), VSliderScalar(). For those three the 'float power=1.0f' version was removed directly as they were most unlikely ever used.
-                       for shared code, you can version check at compile-time with `#if IMGUI_VERSION_NUM >= 17704`.
-                     - obsoleted use of v_min > v_max in DragInt, DragFloat, DragScalar to lock edits (introduced in 1.73, was not demoed nor documented very), will be replaced by a more generic ReadOnly feature. You may use the ImGuiSliderFlags_ReadOnly internal flag in the meantime.
- - 2020/06/23 (1.77) - removed BeginPopupContextWindow(const char*, int mouse_button, bool also_over_items) in favor of BeginPopupContextWindow(const char*, ImGuiPopupFlags flags) with ImGuiPopupFlags_NoOverItems.
- - 2020/06/15 (1.77) - renamed OpenPopupOnItemClick() to OpenPopupContextItem(). Kept inline redirection function (will obsolete). [NOTE: THIS WAS REVERTED IN 1.79]
- - 2020/06/15 (1.77) - removed CalcItemRectClosestPoint() entry point which was made obsolete and asserting in December 2017.
- - 2020/04/23 (1.77) - removed unnecessary ID (first arg) of ImFontAtlas::AddCustomRectRegular().
- - 2020/01/22 (1.75) - ImDrawList::AddCircle()/AddCircleFilled() functions don't accept negative radius any more.
- - 2019/12/17 (1.75) - [undid this change in 1.76] made Columns() limited to 64 columns by asserting above that limit. While the current code technically supports it, future code may not so we're putting the restriction ahead.
- - 2019/12/13 (1.75) - [imgui_internal.h] changed ImRect() default constructor initializes all fields to 0.0f instead of (FLT_MAX,FLT_MAX,-FLT_MAX,-FLT_MAX). If you used ImRect::Add() to create bounding boxes by adding multiple points into it, you may need to fix your initial value.
- - 2019/12/08 (1.75) - removed redirecting functions/enums that were marked obsolete in 1.53 (December 2017):
-                       - ShowTestWindow()                    -> use ShowDemoWindow()
-                       - IsRootWindowFocused()               -> use IsWindowFocused(ImGuiFocusedFlags_RootWindow)
-                       - IsRootWindowOrAnyChildFocused()     -> use IsWindowFocused(ImGuiFocusedFlags_RootAndChildWindows)
-                       - SetNextWindowContentWidth(w)        -> use SetNextWindowContentSize(ImVec2(w, 0.0f)
-                       - GetItemsLineHeightWithSpacing()     -> use GetFrameHeightWithSpacing()
-                       - ImGuiCol_ChildWindowBg              -> use ImGuiCol_ChildBg
-                       - ImGuiStyleVar_ChildWindowRounding   -> use ImGuiStyleVar_ChildRounding
-                       - ImGuiTreeNodeFlags_AllowOverlapMode -> use ImGuiTreeNodeFlags_AllowItemOverlap
-                       - IMGUI_DISABLE_TEST_WINDOWS          -> use IMGUI_DISABLE_DEMO_WINDOWS
- - 2019/12/08 (1.75) - obsoleted calling ImDrawList::PrimReserve() with a negative count (which was vaguely documented and rarely if ever used). Instead, we added an explicit PrimUnreserve() API.
- - 2019/12/06 (1.75) - removed implicit default parameter to IsMouseDragging(int button = 0) to be consistent with other mouse functions (none of the other functions have it).
- - 2019/11/21 (1.74) - ImFontAtlas::AddCustomRectRegular() now requires an ID larger than 0x110000 (instead of 0x10000) to conform with supporting Unicode planes 1-16 in a future update. ID below 0x110000 will now assert.
- - 2019/11/19 (1.74) - renamed IMGUI_DISABLE_FORMAT_STRING_FUNCTIONS to IMGUI_DISABLE_DEFAULT_FORMAT_FUNCTIONS for consistency.
- - 2019/11/19 (1.74) - renamed IMGUI_DISABLE_MATH_FUNCTIONS to IMGUI_DISABLE_DEFAULT_MATH_FUNCTIONS for consistency.
- - 2019/10/22 (1.74) - removed redirecting functions/enums that were marked obsolete in 1.52 (October 2017):
-                       - Begin() [old 5 args version]        -> use Begin() [3 args], use SetNextWindowSize() SetNextWindowBgAlpha() if needed
-                       - IsRootWindowOrAnyChildHovered()     -> use IsWindowHovered(ImGuiHoveredFlags_RootAndChildWindows)
-                       - AlignFirstTextHeightToWidgets()     -> use AlignTextToFramePadding()
-                       - SetNextWindowPosCenter()            -> use SetNextWindowPos() with a pivot of (0.5f, 0.5f)
-                       - ImFont::Glyph                       -> use ImFontGlyph
- - 2019/10/14 (1.74) - inputs: Fixed a miscalculation in the keyboard/mouse "typematic" repeat delay/rate calculation, used by keys and e.g. repeating mouse buttons as well as the GetKeyPressedAmount() function.
-                       if you were using a non-default value for io.KeyRepeatRate (previous default was 0.250), you can add +io.KeyRepeatDelay to it to compensate for the fix.
-                       The function was triggering on: 0.0 and (delay+rate*N) where (N>=1). Fixed formula responds to (N>=0). Effectively it made io.KeyRepeatRate behave like it was set to (io.KeyRepeatRate + io.KeyRepeatDelay).
-                       If you never altered io.KeyRepeatRate nor used GetKeyPressedAmount() this won't affect you.
- - 2019/07/15 (1.72) - removed TreeAdvanceToLabelPos() which is rarely used and only does SetCursorPosX(GetCursorPosX() + GetTreeNodeToLabelSpacing()). Kept redirection function (will obsolete).
- - 2019/07/12 (1.72) - renamed ImFontAtlas::CustomRect to ImFontAtlasCustomRect. Kept redirection typedef (will obsolete).
- - 2019/06/14 (1.72) - removed redirecting functions/enums names that were marked obsolete in 1.51 (June 2017): ImGuiCol_Column*, ImGuiSetCond_*, IsItemHoveredRect(), IsPosHoveringAnyWindow(), IsMouseHoveringAnyWindow(), IsMouseHoveringWindow(), IMGUI_ONCE_UPON_A_FRAME. Grep this log for details and new names, or see how they were implemented until 1.71.
- - 2019/06/07 (1.71) - rendering of child window outer decorations (bg color, border, scrollbars) is now performed as part of the parent window. If you have
-                       overlapping child windows in a same parent, and relied on their relative z-order to be mapped to their submission order, this will affect your rendering.
-                       This optimization is disabled if the parent window has no visual output, because it appears to be the most common situation leading to the creation of overlapping child windows.
-                       Please reach out if you are affected.
- - 2019/05/13 (1.71) - renamed SetNextTreeNodeOpen() to SetNextItemOpen(). Kept inline redirection function (will obsolete).
- - 2019/05/11 (1.71) - changed io.AddInputCharacter(unsigned short c) signature to io.AddInputCharacter(unsigned int c).
- - 2019/04/29 (1.70) - improved ImDrawList thick strokes (>1.0f) preserving correct thickness up to 90 degrees angles (e.g. rectangles). If you have custom rendering using thick lines, they will appear thicker now.
- - 2019/04/29 (1.70) - removed GetContentRegionAvailWidth(), use GetContentRegionAvail().x instead. Kept inline redirection function (will obsolete).
- - 2019/03/04 (1.69) - renamed GetOverlayDrawList() to GetForegroundDrawList(). Kept redirection function (will obsolete).
- - 2019/02/26 (1.69) - renamed ImGuiColorEditFlags_RGB/ImGuiColorEditFlags_HSV/ImGuiColorEditFlags_HEX to ImGuiColorEditFlags_DisplayRGB/ImGuiColorEditFlags_DisplayHSV/ImGuiColorEditFlags_DisplayHex. Kept redirection enums (will obsolete).
- - 2019/02/14 (1.68) - made it illegal/assert when io.DisplayTime == 0.0f (with an exception for the first frame). If for some reason your time step calculation gives you a zero value, replace it with an arbitrarily small value!
- - 2019/02/01 (1.68) - removed io.DisplayVisibleMin/DisplayVisibleMax (which were marked obsolete and removed from viewport/docking branch already).
- - 2019/01/06 (1.67) - renamed io.InputCharacters[], marked internal as was always intended. Please don't access directly, and use AddInputCharacter() instead!
- - 2019/01/06 (1.67) - renamed ImFontAtlas::GlyphRangesBuilder to ImFontGlyphRangesBuilder. Kept redirection typedef (will obsolete).
- - 2018/12/20 (1.67) - made it illegal to call Begin("") with an empty string. This somehow half-worked before but had various undesirable side-effects.
- - 2018/12/10 (1.67) - renamed io.ConfigResizeWindowsFromEdges to io.ConfigWindowsResizeFromEdges as we are doing a large pass on configuration flags.
- - 2018/10/12 (1.66) - renamed misc/stl/imgui_stl.* to misc/cpp/imgui_stdlib.* in prevision for other C++ helper files.
- - 2018/09/28 (1.66) - renamed SetScrollHere() to SetScrollHereY(). Kept redirection function (will obsolete).
- - 2018/09/06 (1.65) - renamed stb_truetype.h to imstb_truetype.h, stb_textedit.h to imstb_textedit.h, and stb_rect_pack.h to imstb_rectpack.h.
-                       If you were conveniently using the imgui copy of those STB headers in your project you will have to update your include paths.
- - 2018/09/05 (1.65) - renamed io.OptCursorBlink/io.ConfigCursorBlink to io.ConfigInputTextCursorBlink. (#1427)
- - 2018/08/31 (1.64) - added imgui_widgets.cpp file, extracted and moved widgets code out of imgui.cpp into imgui_widgets.cpp. Re-ordered some of the code remaining in imgui.cpp.
-                       NONE OF THE FUNCTIONS HAVE CHANGED. THE CODE IS SEMANTICALLY 100% IDENTICAL, BUT _EVERY_ FUNCTION HAS BEEN MOVED.
-                       Because of this, any local modifications to imgui.cpp will likely conflict when you update. Read docs/CHANGELOG.txt for suggestions.
- - 2018/08/22 (1.63) - renamed IsItemDeactivatedAfterChange() to IsItemDeactivatedAfterEdit() for consistency with new IsItemEdited() API. Kept redirection function (will obsolete soonish as IsItemDeactivatedAfterChange() is very recent).
- - 2018/08/21 (1.63) - renamed ImGuiTextEditCallback to ImGuiInputTextCallback, ImGuiTextEditCallbackData to ImGuiInputTextCallbackData for consistency. Kept redirection types (will obsolete).
- - 2018/08/21 (1.63) - removed ImGuiInputTextCallbackData::ReadOnly since it is a duplication of (ImGuiInputTextCallbackData::Flags & ImGuiInputTextFlags_ReadOnly).
- - 2018/08/01 (1.63) - removed per-window ImGuiWindowFlags_ResizeFromAnySide beta flag in favor of a global io.ConfigResizeWindowsFromEdges [update 1.67 renamed to ConfigWindowsResizeFromEdges] to enable the feature.
- - 2018/08/01 (1.63) - renamed io.OptCursorBlink to io.ConfigCursorBlink [-> io.ConfigInputTextCursorBlink in 1.65], io.OptMacOSXBehaviors to ConfigMacOSXBehaviors for consistency.
- - 2018/07/22 (1.63) - changed ImGui::GetTime() return value from float to double to avoid accumulating floating point imprecisions over time.
- - 2018/07/08 (1.63) - style: renamed ImGuiCol_ModalWindowDarkening to ImGuiCol_ModalWindowDimBg for consistency with other features. Kept redirection enum (will obsolete).
- - 2018/06/08 (1.62) - examples: the imgui_impl_XXX files have been split to separate platform (Win32, GLFW, SDL2, etc.) from renderer (DX11, OpenGL, Vulkan,  etc.).
-                       old backends will still work as is, however prefer using the separated backends as they will be updated to support multi-viewports.
-                       when adopting new backends follow the main.cpp code of your preferred examples/ folder to know which functions to call.
-                       in particular, note that old backends called ImGui::NewFrame() at the end of their ImGui_ImplXXXX_NewFrame() function.
- - 2018/06/06 (1.62) - renamed GetGlyphRangesChinese() to GetGlyphRangesChineseFull() to distinguish other variants and discourage using the full set.
- - 2018/06/06 (1.62) - TreeNodeEx()/TreeNodeBehavior(): the ImGuiTreeNodeFlags_CollapsingHeader helper now include the ImGuiTreeNodeFlags_NoTreePushOnOpen flag. See Changelog for details.
- - 2018/05/03 (1.61) - DragInt(): the default compile-time format string has been changed from "%.0f" to "%d", as we are not using integers internally any more.
-                       If you used DragInt() with custom format strings, make sure you change them to use %d or an integer-compatible format.
-                       To honor backward-compatibility, the DragInt() code will currently parse and modify format strings to replace %*f with %d, giving time to users to upgrade their code.
-                       If you have IMGUI_DISABLE_OBSOLETE_FUNCTIONS enabled, the code will instead assert! You may run a reg-exp search on your codebase for e.g. "DragInt.*%f" to help you find them.
- - 2018/04/28 (1.61) - obsoleted InputFloat() functions taking an optional "int decimal_precision" in favor of an equivalent and more flexible "const char* format",
-                       consistent with other functions. Kept redirection functions (will obsolete).
- - 2018/04/09 (1.61) - IM_DELETE() helper function added in 1.60 doesn't clear the input _pointer_ reference, more consistent with expectation and allows passing r-value.
- - 2018/03/20 (1.60) - renamed io.WantMoveMouse to io.WantSetMousePos for consistency and ease of understanding (was added in 1.52, _not_ used by core and only honored by some backend ahead of merging the Nav branch).
- - 2018/03/12 (1.60) - removed ImGuiCol_CloseButton, ImGuiCol_CloseButtonActive, ImGuiCol_CloseButtonHovered as the closing cross uses regular button colors now.
- - 2018/03/08 (1.60) - changed ImFont::DisplayOffset.y to default to 0 instead of +1. Fixed rounding of Ascent/Descent to match TrueType renderer. If you were adding or subtracting to ImFont::DisplayOffset check if your fonts are correctly aligned vertically.
- - 2018/03/03 (1.60) - renamed ImGuiStyleVar_Count_ to ImGuiStyleVar_COUNT and ImGuiMouseCursor_Count_ to ImGuiMouseCursor_COUNT for consistency with other public enums.
- - 2018/02/18 (1.60) - BeginDragDropSource(): temporarily removed the optional mouse_button=0 parameter because it is not really usable in many situations at the moment.
- - 2018/02/16 (1.60) - obsoleted the io.RenderDrawListsFn callback, you can call your graphics engine render function after ImGui::Render(). Use ImGui::GetDrawData() to retrieve the ImDrawData* to display.
- - 2018/02/07 (1.60) - reorganized context handling to be more explicit,
-                       - YOU NOW NEED TO CALL ImGui::CreateContext() AT THE BEGINNING OF YOUR APP, AND CALL ImGui::DestroyContext() AT THE END.
-                       - removed Shutdown() function, as DestroyContext() serve this purpose.
-                       - you may pass a ImFontAtlas* pointer to CreateContext() to share a font atlas between contexts. Otherwise CreateContext() will create its own font atlas instance.
-                       - removed allocator parameters from CreateContext(), they are now setup with SetAllocatorFunctions(), and shared by all contexts.
-                       - removed the default global context and font atlas instance, which were confusing for users of DLL reloading and users of multiple contexts.
- - 2018/01/31 (1.60) - moved sample TTF files from extra_fonts/ to misc/fonts/. If you loaded files directly from the imgui repo you may need to update your paths.
- - 2018/01/11 (1.60) - obsoleted IsAnyWindowHovered() in favor of IsWindowHovered(ImGuiHoveredFlags_AnyWindow). Kept redirection function (will obsolete).
- - 2018/01/11 (1.60) - obsoleted IsAnyWindowFocused() in favor of IsWindowFocused(ImGuiFocusedFlags_AnyWindow). Kept redirection function (will obsolete).
- - 2018/01/03 (1.60) - renamed ImGuiSizeConstraintCallback to ImGuiSizeCallback, ImGuiSizeConstraintCallbackData to ImGuiSizeCallbackData.
- - 2017/12/29 (1.60) - removed CalcItemRectClosestPoint() which was weird and not really used by anyone except demo code. If you need it it's easy to replicate on your side.
- - 2017/12/24 (1.53) - renamed the emblematic ShowTestWindow() function to ShowDemoWindow(). Kept redirection function (will obsolete).
- - 2017/12/21 (1.53) - ImDrawList: renamed style.AntiAliasedShapes to style.AntiAliasedFill for consistency and as a way to explicitly break code that manipulate those flag at runtime. You can now manipulate ImDrawList::Flags
- - 2017/12/21 (1.53) - ImDrawList: removed 'bool anti_aliased = true' final parameter of ImDrawList::AddPolyline() and ImDrawList::AddConvexPolyFilled(). Prefer manipulating ImDrawList::Flags if you need to toggle them during the frame.
- - 2017/12/14 (1.53) - using the ImGuiWindowFlags_NoScrollWithMouse flag on a child window forwards the mouse wheel event to the parent window, unless either ImGuiWindowFlags_NoInputs or ImGuiWindowFlags_NoScrollbar are also set.
- - 2017/12/13 (1.53) - renamed GetItemsLineHeightWithSpacing() to GetFrameHeightWithSpacing(). Kept redirection function (will obsolete).
- - 2017/12/13 (1.53) - obsoleted IsRootWindowFocused() in favor of using IsWindowFocused(ImGuiFocusedFlags_RootWindow). Kept redirection function (will obsolete).
-                     - obsoleted IsRootWindowOrAnyChildFocused() in favor of using IsWindowFocused(ImGuiFocusedFlags_RootAndChildWindows). Kept redirection function (will obsolete).
- - 2017/12/12 (1.53) - renamed ImGuiTreeNodeFlags_AllowOverlapMode to ImGuiTreeNodeFlags_AllowItemOverlap. Kept redirection enum (will obsolete).
- - 2017/12/10 (1.53) - removed SetNextWindowContentWidth(), prefer using SetNextWindowContentSize(). Kept redirection function (will obsolete).
- - 2017/11/27 (1.53) - renamed ImGuiTextBuffer::append() helper to appendf(), appendv() to appendfv(). If you copied the 'Log' demo in your code, it uses appendv() so that needs to be renamed.
- - 2017/11/18 (1.53) - Style, Begin: removed ImGuiWindowFlags_ShowBorders window flag. Borders are now fully set up in the ImGuiStyle structure (see e.g. style.FrameBorderSize, style.WindowBorderSize). Use ImGui::ShowStyleEditor() to look them up.
-                       Please note that the style system will keep evolving (hopefully stabilizing in Q1 2018), and so custom styles will probably subtly break over time. It is recommended you use the StyleColorsClassic(), StyleColorsDark(), StyleColorsLight() functions.
- - 2017/11/18 (1.53) - Style: removed ImGuiCol_ComboBg in favor of combo boxes using ImGuiCol_PopupBg for consistency.
- - 2017/11/18 (1.53) - Style: renamed ImGuiCol_ChildWindowBg to ImGuiCol_ChildBg.
- - 2017/11/18 (1.53) - Style: renamed style.ChildWindowRounding to style.ChildRounding, ImGuiStyleVar_ChildWindowRounding to ImGuiStyleVar_ChildRounding.
- - 2017/11/02 (1.53) - obsoleted IsRootWindowOrAnyChildHovered() in favor of using IsWindowHovered(ImGuiHoveredFlags_RootAndChildWindows);
- - 2017/10/24 (1.52) - renamed IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCS/IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCS to IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCTIONS/IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCTIONS for consistency.
- - 2017/10/20 (1.52) - changed IsWindowHovered() default parameters behavior to return false if an item is active in another window (e.g. click-dragging item from another window to this window). You can use the newly introduced IsWindowHovered() flags to requests this specific behavior if you need it.
- - 2017/10/20 (1.52) - marked IsItemHoveredRect()/IsMouseHoveringWindow() as obsolete, in favor of using the newly introduced flags for IsItemHovered() and IsWindowHovered(). See https://github.com/ocornut/imgui/issues/1382 for details.
-                       removed the IsItemRectHovered()/IsWindowRectHovered() names introduced in 1.51 since they were merely more consistent names for the two functions we are now obsoleting.
-                         IsItemHoveredRect()        --> IsItemHovered(ImGuiHoveredFlags_RectOnly)
-                         IsMouseHoveringAnyWindow() --> IsWindowHovered(ImGuiHoveredFlags_AnyWindow)
-                         IsMouseHoveringWindow()    --> IsWindowHovered(ImGuiHoveredFlags_AllowWhenBlockedByPopup | ImGuiHoveredFlags_AllowWhenBlockedByActiveItem) [weird, old behavior]
- - 2017/10/17 (1.52) - marked the old 5-parameters version of Begin() as obsolete (still available). Use SetNextWindowSize()+Begin() instead!
- - 2017/10/11 (1.52) - renamed AlignFirstTextHeightToWidgets() to AlignTextToFramePadding(). Kept inline redirection function (will obsolete).
- - 2017/09/26 (1.52) - renamed ImFont::Glyph to ImFontGlyph. Kept redirection typedef (will obsolete).
- - 2017/09/25 (1.52) - removed SetNextWindowPosCenter() because SetNextWindowPos() now has the optional pivot information to do the same and more. Kept redirection function (will obsolete).
- - 2017/08/25 (1.52) - io.MousePos needs to be set to ImVec2(-FLT_MAX,-FLT_MAX) when mouse is unavailable/missing. Previously ImVec2(-1,-1) was enough but we now accept negative mouse coordinates. In your backend if you need to support unavailable mouse, make sure to replace "io.MousePos = ImVec2(-1,-1)" with "io.MousePos = ImVec2(-FLT_MAX,-FLT_MAX)".
- - 2017/08/22 (1.51) - renamed IsItemHoveredRect() to IsItemRectHovered(). Kept inline redirection function (will obsolete). -> (1.52) use IsItemHovered(ImGuiHoveredFlags_RectOnly)!
-                     - renamed IsMouseHoveringAnyWindow() to IsAnyWindowHovered() for consistency. Kept inline redirection function (will obsolete).
-                     - renamed IsMouseHoveringWindow() to IsWindowRectHovered() for consistency. Kept inline redirection function (will obsolete).
- - 2017/08/20 (1.51) - renamed GetStyleColName() to GetStyleColorName() for consistency.
- - 2017/08/20 (1.51) - added PushStyleColor(ImGuiCol idx, ImU32 col) overload, which _might_ cause an "ambiguous call" compilation error if you are using ImColor() with implicit cast. Cast to ImU32 or ImVec4 explicily to fix.
- - 2017/08/15 (1.51) - marked the weird IMGUI_ONCE_UPON_A_FRAME helper macro as obsolete. prefer using the more explicit ImGuiOnceUponAFrame type.
- - 2017/08/15 (1.51) - changed parameter order for BeginPopupContextWindow() from (const char*,int buttons,bool also_over_items) to (const char*,int buttons,bool also_over_items). Note that most calls relied on default parameters completely.
- - 2017/08/13 (1.51) - renamed ImGuiCol_Column to ImGuiCol_Separator, ImGuiCol_ColumnHovered to ImGuiCol_SeparatorHovered, ImGuiCol_ColumnActive to ImGuiCol_SeparatorActive. Kept redirection enums (will obsolete).
- - 2017/08/11 (1.51) - renamed ImGuiSetCond_Always to ImGuiCond_Always, ImGuiSetCond_Once to ImGuiCond_Once, ImGuiSetCond_FirstUseEver to ImGuiCond_FirstUseEver, ImGuiSetCond_Appearing to ImGuiCond_Appearing. Kept redirection enums (will obsolete).
- - 2017/08/09 (1.51) - removed ValueColor() helpers, they are equivalent to calling Text(label) + SameLine() + ColorButton().
- - 2017/08/08 (1.51) - removed ColorEditMode() and ImGuiColorEditMode in favor of ImGuiColorEditFlags and parameters to the various Color*() functions. The SetColorEditOptions() allows to initialize default but the user can still change them with right-click context menu.
-                     - changed prototype of 'ColorEdit4(const char* label, float col[4], bool show_alpha = true)' to 'ColorEdit4(const char* label, float col[4], ImGuiColorEditFlags flags = 0)', where passing flags = 0x01 is a safe no-op (hello dodgy backward compatibility!). - check and run the demo window, under "Color/Picker Widgets", to understand the various new options.
-                     - changed prototype of rarely used 'ColorButton(ImVec4 col, bool small_height = false, bool outline_border = true)' to 'ColorButton(const char* desc_id, ImVec4 col, ImGuiColorEditFlags flags = 0, ImVec2 size = ImVec2(0, 0))'
- - 2017/07/20 (1.51) - removed IsPosHoveringAnyWindow(ImVec2), which was partly broken and misleading. ASSERT + redirect user to io.WantCaptureMouse
- - 2017/05/26 (1.50) - removed ImFontConfig::MergeGlyphCenterV in favor of a more multipurpose ImFontConfig::GlyphOffset.
- - 2017/05/01 (1.50) - renamed ImDrawList::PathFill() (rarely used directly) to ImDrawList::PathFillConvex() for clarity.
- - 2016/11/06 (1.50) - BeginChild(const char*) now applies the stack id to the provided label, consistently with other functions as it should always have been. It shouldn't affect you unless (extremely unlikely) you were appending multiple times to a same child from different locations of the stack id. If that's the case, generate an id with GetID() and use it instead of passing string to BeginChild().
- - 2016/10/15 (1.50) - avoid 'void* user_data' parameter to io.SetClipboardTextFn/io.GetClipboardTextFn pointers. We pass io.ClipboardUserData to it.
- - 2016/09/25 (1.50) - style.WindowTitleAlign is now a ImVec2 (ImGuiAlign enum was removed). set to (0.5f,0.5f) for horizontal+vertical centering, (0.0f,0.0f) for upper-left, etc.
- - 2016/07/30 (1.50) - SameLine(x) with x>0.0f is now relative to left of column/group if any, and not always to left of window. This was sort of always the intent and hopefully, breakage should be minimal.
- - 2016/05/12 (1.49) - title bar (using ImGuiCol_TitleBg/ImGuiCol_TitleBgActive colors) isn't rendered over a window background (ImGuiCol_WindowBg color) anymore.
-                       If your TitleBg/TitleBgActive alpha was 1.0f or you are using the default theme it will not affect you, otherwise if <1.0f you need to tweak your custom theme to readjust for the fact that we don't draw a WindowBg background behind the title bar.
-                       This helper function will convert an old TitleBg/TitleBgActive color into a new one with the same visual output, given the OLD color and the OLD WindowBg color:
-                       ImVec4 ConvertTitleBgCol(const ImVec4& win_bg_col, const ImVec4& title_bg_col) { float new_a = 1.0f - ((1.0f - win_bg_col.w) * (1.0f - title_bg_col.w)), k = title_bg_col.w / new_a; return ImVec4((win_bg_col.x * win_bg_col.w + title_bg_col.x) * k, (win_bg_col.y * win_bg_col.w + title_bg_col.y) * k, (win_bg_col.z * win_bg_col.w + title_bg_col.z) * k, new_a); }
-                       If this is confusing, pick the RGB value from title bar from an old screenshot and apply this as TitleBg/TitleBgActive. Or you may just create TitleBgActive from a tweaked TitleBg color.
- - 2016/05/07 (1.49) - removed confusing set of GetInternalState(), GetInternalStateSize(), SetInternalState() functions. Now using CreateContext(), DestroyContext(), GetCurrentContext(), SetCurrentContext().
- - 2016/05/02 (1.49) - renamed SetNextTreeNodeOpened() to SetNextTreeNodeOpen(), no redirection.
- - 2016/05/01 (1.49) - obsoleted old signature of CollapsingHeader(const char* label, const char* str_id = NULL, bool display_frame = true, bool default_open = false) as extra parameters were badly designed and rarely used. You can replace the "default_open = true" flag in new API with CollapsingHeader(label, ImGuiTreeNodeFlags_DefaultOpen).
- - 2016/04/26 (1.49) - changed ImDrawList::PushClipRect(ImVec4 rect) to ImDrawList::PushClipRect(Imvec2 min,ImVec2 max,bool intersect_with_current_clip_rect=false). Note that higher-level ImGui::PushClipRect() is preferable because it will clip at logic/widget level, whereas ImDrawList::PushClipRect() only affect your renderer.
- - 2016/04/03 (1.48) - removed style.WindowFillAlphaDefault setting which was redundant. Bake default BG alpha inside style.Colors[ImGuiCol_WindowBg] and all other Bg color values. (ref GitHub issue #337).
- - 2016/04/03 (1.48) - renamed ImGuiCol_TooltipBg to ImGuiCol_PopupBg, used by popups/menus and tooltips. popups/menus were previously using ImGuiCol_WindowBg. (ref github issue #337)
- - 2016/03/21 (1.48) - renamed GetWindowFont() to GetFont(), GetWindowFontSize() to GetFontSize(). Kept inline redirection function (will obsolete).
- - 2016/03/02 (1.48) - InputText() completion/history/always callbacks: if you modify the text buffer manually (without using DeleteChars()/InsertChars() helper) you need to maintain the BufTextLen field. added an assert.
- - 2016/01/23 (1.48) - fixed not honoring exact width passed to PushItemWidth(), previously it would add extra FramePadding.x*2 over that width. if you had manual pixel-perfect alignment in place it might affect you.
- - 2015/12/27 (1.48) - fixed ImDrawList::AddRect() which used to render a rectangle 1 px too large on each axis.
- - 2015/12/04 (1.47) - renamed Color() helpers to ValueColor() - dangerously named, rarely used and probably to be made obsolete.
- - 2015/08/29 (1.45) - with the addition of horizontal scrollbar we made various fixes to inconsistencies with dealing with cursor position.
-                       GetCursorPos()/SetCursorPos() functions now include the scrolled amount. It shouldn't affect the majority of users, but take note that SetCursorPosX(100.0f) puts you at +100 from the starting x position which may include scrolling, not at +100 from the window left side.
-                       GetContentRegionMax()/GetWindowContentRegionMin()/GetWindowContentRegionMax() functions allow include the scrolled amount. Typically those were used in cases where no scrolling would happen so it may not be a problem, but watch out!
- - 2015/08/29 (1.45) - renamed style.ScrollbarWidth to style.ScrollbarSize
- - 2015/08/05 (1.44) - split imgui.cpp into extra files: imgui_demo.cpp imgui_draw.cpp imgui_internal.h that you need to add to your project.
- - 2015/07/18 (1.44) - fixed angles in ImDrawList::PathArcTo(), PathArcToFast() (introduced in 1.43) being off by an extra PI for no justifiable reason
- - 2015/07/14 (1.43) - add new ImFontAtlas::AddFont() API. For the old AddFont***, moved the 'font_no' parameter of ImFontAtlas::AddFont** functions to the ImFontConfig structure.
-                       you need to render your textured triangles with bilinear filtering to benefit from sub-pixel positioning of text.
- - 2015/07/08 (1.43) - switched rendering data to use indexed rendering. this is saving a fair amount of CPU/GPU and enables us to get anti-aliasing for a marginal cost.
-                       this necessary change will break your rendering function! the fix should be very easy. sorry for that :(
-                     - if you are using a vanilla copy of one of the imgui_impl_XXX.cpp provided in the example, you just need to update your copy and you can ignore the rest.
-                     - the signature of the io.RenderDrawListsFn handler has changed!
-                       old: ImGui_XXXX_RenderDrawLists(ImDrawList** const cmd_lists, int cmd_lists_count)
-                       new: ImGui_XXXX_RenderDrawLists(ImDrawData* draw_data).
-                         parameters: 'cmd_lists' becomes 'draw_data->CmdLists', 'cmd_lists_count' becomes 'draw_data->CmdListsCount'
-                         ImDrawList: 'commands' becomes 'CmdBuffer', 'vtx_buffer' becomes 'VtxBuffer', 'IdxBuffer' is new.
-                         ImDrawCmd:  'vtx_count' becomes 'ElemCount', 'clip_rect' becomes 'ClipRect', 'user_callback' becomes 'UserCallback', 'texture_id' becomes 'TextureId'.
-                     - each ImDrawList now contains both a vertex buffer and an index buffer. For each command, render ElemCount/3 triangles using indices from the index buffer.
-                     - if you REALLY cannot render indexed primitives, you can call the draw_data->DeIndexAllBuffers() method to de-index the buffers. This is slow and a waste of CPU/GPU. Prefer using indexed rendering!
-                     - refer to code in the examples/ folder or ask on the GitHub if you are unsure of how to upgrade. please upgrade!
- - 2015/07/10 (1.43) - changed SameLine() parameters from int to float.
- - 2015/07/02 (1.42) - renamed SetScrollPosHere() to SetScrollFromCursorPos(). Kept inline redirection function (will obsolete).
- - 2015/07/02 (1.42) - renamed GetScrollPosY() to GetScrollY(). Necessary to reduce confusion along with other scrolling functions, because positions (e.g. cursor position) are not equivalent to scrolling amount.
- - 2015/06/14 (1.41) - changed ImageButton() default bg_col parameter from (0,0,0,1) (black) to (0,0,0,0) (transparent) - makes a difference when texture have transparence
- - 2015/06/14 (1.41) - changed Selectable() API from (label, selected, size) to (label, selected, flags, size). Size override should have been rarely used. Sorry!
- - 2015/05/31 (1.40) - renamed GetWindowCollapsed() to IsWindowCollapsed() for consistency. Kept inline redirection function (will obsolete).
- - 2015/05/31 (1.40) - renamed IsRectClipped() to IsRectVisible() for consistency. Note that return value is opposite! Kept inline redirection function (will obsolete).
- - 2015/05/27 (1.40) - removed the third 'repeat_if_held' parameter from Button() - sorry! it was rarely used and inconsistent. Use PushButtonRepeat(true) / PopButtonRepeat() to enable repeat on desired buttons.
- - 2015/05/11 (1.40) - changed BeginPopup() API, takes a string identifier instead of a bool. ImGui needs to manage the open/closed state of popups. Call OpenPopup() to actually set the "open" state of a popup. BeginPopup() returns true if the popup is opened.
- - 2015/05/03 (1.40) - removed style.AutoFitPadding, using style.WindowPadding makes more sense (the default values were already the same).
- - 2015/04/13 (1.38) - renamed IsClipped() to IsRectClipped(). Kept inline redirection function until 1.50.
- - 2015/04/09 (1.38) - renamed ImDrawList::AddArc() to ImDrawList::AddArcFast() for compatibility with future API
- - 2015/04/03 (1.38) - removed ImGuiCol_CheckHovered, ImGuiCol_CheckActive, replaced with the more general ImGuiCol_FrameBgHovered, ImGuiCol_FrameBgActive.
- - 2014/04/03 (1.38) - removed support for passing -FLT_MAX..+FLT_MAX as the range for a SliderFloat(). Use DragFloat() or Inputfloat() instead.
- - 2015/03/17 (1.36) - renamed GetItemBoxMin()/GetItemBoxMax()/IsMouseHoveringBox() to GetItemRectMin()/GetItemRectMax()/IsMouseHoveringRect(). Kept inline redirection function until 1.50.
- - 2015/03/15 (1.36) - renamed style.TreeNodeSpacing to style.IndentSpacing, ImGuiStyleVar_TreeNodeSpacing to ImGuiStyleVar_IndentSpacing
- - 2015/03/13 (1.36) - renamed GetWindowIsFocused() to IsWindowFocused(). Kept inline redirection function until 1.50.
- - 2015/03/08 (1.35) - renamed style.ScrollBarWidth to style.ScrollbarWidth (casing)
- - 2015/02/27 (1.34) - renamed OpenNextNode(bool) to SetNextTreeNodeOpened(bool, ImGuiSetCond). Kept inline redirection function until 1.50.
- - 2015/02/27 (1.34) - renamed ImGuiSetCondition_*** to ImGuiSetCond_***, and _FirstUseThisSession becomes _Once.
- - 2015/02/11 (1.32) - changed text input callback ImGuiTextEditCallback return type from void-->int. reserved for future use, return 0 for now.
- - 2015/02/10 (1.32) - renamed GetItemWidth() to CalcItemWidth() to clarify its evolving behavior
- - 2015/02/08 (1.31) - renamed GetTextLineSpacing() to GetTextLineHeightWithSpacing()
- - 2015/02/01 (1.31) - removed IO.MemReallocFn (unused)
- - 2015/01/19 (1.30) - renamed ImGuiStorage::GetIntPtr()/GetFloatPtr() to GetIntRef()/GetIntRef() because Ptr was conflicting with actual pointer storage functions.
- - 2015/01/11 (1.30) - big font/image API change! now loads TTF file. allow for multiple fonts. no need for a PNG loader.
- - 2015/01/11 (1.30) - removed GetDefaultFontData(). uses io.Fonts->GetTextureData*() API to retrieve uncompressed pixels.
-                       - old:  const void* png_data; unsigned int png_size; ImGui::GetDefaultFontData(NULL, NULL, &png_data, &png_size); [..Upload texture to GPU..];
-                       - new:  unsigned char* pixels; int width, height; io.Fonts->GetTexDataAsRGBA32(&pixels, &width, &height); [..Upload texture to GPU..]; io.Fonts->SetTexID(YourTexIdentifier);
-                       you now have more flexibility to load multiple TTF fonts and manage the texture buffer for internal needs. It is now recommended that you sample the font texture with bilinear interpolation.
- - 2015/01/11 (1.30) - added texture identifier in ImDrawCmd passed to your render function (we can now render images). make sure to call io.Fonts->SetTexID()
- - 2015/01/11 (1.30) - removed IO.PixelCenterOffset (unnecessary, can be handled in user projection matrix)
- - 2015/01/11 (1.30) - removed ImGui::IsItemFocused() in favor of ImGui::IsItemActive() which handles all widgets
- - 2014/12/10 (1.18) - removed SetNewWindowDefaultPos() in favor of new generic API SetNextWindowPos(pos, ImGuiSetCondition_FirstUseEver)
- - 2014/11/28 (1.17) - moved IO.Font*** options to inside the IO.Font-> structure (FontYOffset, FontTexUvForWhite, FontBaseScale, FontFallbackGlyph)
- - 2014/11/26 (1.17) - reworked syntax of IMGUI_ONCE_UPON_A_FRAME helper macro to increase compiler compatibility
- - 2014/11/07 (1.15) - renamed IsHovered() to IsItemHovered()
- - 2014/10/02 (1.14) - renamed IMGUI_INCLUDE_IMGUI_USER_CPP to IMGUI_INCLUDE_IMGUI_USER_INL and imgui_user.cpp to imgui_user.inl (more IDE friendly)
- - 2014/09/25 (1.13) - removed 'text_end' parameter from IO.SetClipboardTextFn (the string is now always zero-terminated for simplicity)
- - 2014/09/24 (1.12) - renamed SetFontScale() to SetWindowFontScale()
- - 2014/09/24 (1.12) - moved IM_MALLOC/IM_REALLOC/IM_FREE preprocessor defines to IO.MemAllocFn/IO.MemReallocFn/IO.MemFreeFn
- - 2014/08/30 (1.09) - removed IO.FontHeight (now computed automatically)
- - 2014/08/30 (1.09) - moved IMGUI_FONT_TEX_UV_FOR_WHITE preprocessor define to IO.FontTexUvForWhite
- - 2014/08/28 (1.09) - changed the behavior of IO.PixelCenterOffset following various rendering fixes

-
- Q&A: Basics
- ===========
-
- Q: Where is the documentation?
- A: This library is poorly documented at the moment and expects the user to be acquainted with C/C++.
-    - Run the examples/ applications and explore them.
-    - Read Getting Started (https://github.com/ocornut/imgui/wiki/Getting-Started) guide.
-    - See demo code in imgui_demo.cpp and particularly the ImGui::ShowDemoWindow() function.
-    - The demo covers most features of Dear ImGui, so you can read the code and see its output.
-    - See documentation and comments at the top of imgui.cpp + effectively imgui.h.
-    - 20+ standalone example applications using e.g. OpenGL/DirectX are provided in the
-      examples/ folder to explain how to integrate Dear ImGui with your own engine/application.
-    - The Wiki (https://github.com/ocornut/imgui/wiki) has many resources and links.
-    - The Glossary (https://github.com/ocornut/imgui/wiki/Glossary) page also may be useful.
-    - Your programming IDE is your friend, find the type or function declaration to find comments
-      associated with it.
-
- Q: What is this library called?
- Q: Which version should I get?
- >> This library is called "Dear ImGui", please don't call it "ImGui" :)
- >> See https://www.dearimgui.com/faq for details.
-
- Q&A: Integration
- ================
-
- Q: How to get started?
- A: Read https://github.com/ocornut/imgui/wiki/Getting-Started. Read 'PROGRAMMER GUIDE' above. Read examples/README.txt.
-
- Q: How can I tell whether to dispatch mouse/keyboard to Dear ImGui or my application?
- A: You should read the 'io.WantCaptureMouse', 'io.WantCaptureKeyboard' and 'io.WantTextInput' flags!
- >> See https://www.dearimgui.com/faq for a fully detailed answer. You really want to read this.
-
- Q. How can I enable keyboard or gamepad controls?
- Q: How can I use this on a machine without mouse, keyboard or screen? (input share, remote display)
- Q: I integrated Dear ImGui in my engine and little squares are showing instead of text...
- Q: I integrated Dear ImGui in my engine and some elements are clipping or disappearing when I move windows around...
- Q: I integrated Dear ImGui in my engine and some elements are displaying outside their expected windows boundaries...
- >> See https://www.dearimgui.com/faq
-
- Q&A: Usage
- ----------
-
- Q: About the ID Stack system..
-   - Why is my widget not reacting when I click on it?
-   - How can I have widgets with an empty label?
-   - How can I have multiple widgets with the same label?
-   - How can I have multiple windows with the same label?
- Q: How can I display an image? What is ImTextureID, how does it work?
- Q: How can I use my own math types instead of ImVec2?
- Q: How can I interact with standard C++ types (such as std::string and std::vector)?
- Q: How can I display custom shapes? (using low-level ImDrawList API)
- >> See https://www.dearimgui.com/faq
-
- Q&A: Fonts, Text
- ================
-
- Q: How should I handle DPI in my application?
- Q: How can I load a different font than the default?
- Q: How can I easily use icons in my application?
- Q: How can I load multiple fonts?
- Q: How can I display and input non-Latin characters such as Chinese, Japanese, Korean, Cyrillic?
- >> See https://www.dearimgui.com/faq and https://github.com/ocornut/imgui/blob/master/docs/FONTS.md
-
- Q&A: Concerns
- =============
-
- Q: Who uses Dear ImGui?
- Q: Can you create elaborate/serious tools with Dear ImGui?
- Q: Can you reskin the look of Dear ImGui?
- Q: Why using C++ (as opposed to C)?
- >> See https://www.dearimgui.com/faq
-
- Q&A: Community
- ==============
-
- Q: How can I help?
- A: - Businesses: please reach out to "omar AT dearimgui DOT com" if you work in a place using Dear ImGui!
-      We can discuss ways for your company to fund development via invoiced technical support, maintenance or sponsoring contacts.
-      This is among the most useful thing you can do for Dear ImGui. With increased funding, we sustain and grow work on this project.
-      Also see https://github.com/ocornut/imgui/wiki/Sponsors
-    - Businesses: you can also purchase licenses for the Dear ImGui Automation/Test Engine.
-    - If you are experienced with Dear ImGui and C++, look at the GitHub issues, look at the Wiki, and see how you want to help and can help!
-    - Disclose your usage of Dear ImGui via a dev blog post, a tweet, a screenshot, a mention somewhere etc.
-      You may post screenshot or links in the gallery threads. Visuals are ideal as they inspire other programmers.
-      But even without visuals, disclosing your use of dear imgui helps the library grow credibility, and help other teams and programmers with taking decisions.
-    - If you have issues or if you need to hack into the library, even if you don't expect any support it is useful that you share your issues (on GitHub or privately).

-// [SECTION] CONTEXT AND MEMORY ALLOCATORS
-//-----------------------------------------------------------------------------
-
-// DLL users:
-// - Heaps and globals are not shared across DLL boundaries!
-// - You will need to call SetCurrentContext() + SetAllocatorFunctions() for each static/DLL boundary you are calling from.
-// - Same applies for hot-reloading mechanisms that are reliant on reloading DLL (note that many hot-reloading mechanisms work without DLL).
-// - Using Dear ImGui via a shared library is not recommended, because of function call overhead and because we don't guarantee backward nor forward ABI compatibility.
-// - Confused? In a debugger: add GImGui to your watch window and notice how its value changes depending on your current location (which DLL boundary you are in).
-
-// Current context pointer. Implicitly used by all Dear ImGui functions. Always assumed to be != NULL.
-// - ImGui::CreateContext() will automatically set this pointer if it is NULL.
-//   Change to a different context by calling ImGui::SetCurrentContext().
-// - Important: Dear ImGui functions are not thread-safe because of this pointer.
-//   If you want thread-safety to allow N threads to access N different contexts:
-//   - Change this variable to use thread local storage so each thread can refer to a different context, in your imconfig.h:
-//         struct ImGuiContext;
-//         extern thread_local ImGuiContext* MyImGuiTLS;
-//         #define GImGui MyImGuiTLS
-//     And then define MyImGuiTLS in one of your cpp files. Note that thread_local is a C++11 keyword, earlier C++ uses compiler-specific keyword.
-//   - Future development aims to make this context pointer explicit to all calls. Also read https://github.com/ocornut/imgui/issues/586
-//   - If you need a finite number of contexts, you may compile and use multiple instances of the ImGui code from a different namespace.
-// - DLL users: read comments above.

-
-// Memory Allocator functions. Use SetAllocatorFunctions() to change them.

-// - May be combined with SetNextWindowSizeConstraints() to set a min/max size for each axis (see "Demo->Child->Auto-resize with Constraints").
-// - Size measurement for a given axis is only performed when the child window is within visible boundaries, or is just appearing.

-//   - You may also use ImGuiChildFlags_AlwaysAutoResize to force an update even when child window is not in view.
-//     HOWEVER PLEASE UNDERSTAND THAT DOING SO WILL PREVENT BeginChild() FROM EVER RETURNING FALSE, disabling benefits of coarse clipping.

-
-// Flags for ImGui::BeginTable()
-// - Important! Sizing policies have complex and subtle side effects, much more so than you would expect.
-//   Read comments/demos carefully + experiment with live demos to get acquainted with them.
-// - The DEFAULT sizing policies are:
-//    - Default to ImGuiTableFlags_SizingFixedFit    if ScrollX is on, or if host window has ImGuiWindowFlags_AlwaysAutoResize.
-//    - Default to ImGuiTableFlags_SizingStretchSame if ScrollX is off.
-// - When ScrollX is off:
-//    - Table defaults to ImGuiTableFlags_SizingStretchSame -> all Columns defaults to ImGuiTableColumnFlags_WidthStretch with same weight.
-//    - Columns sizing policy allowed: Stretch (default), Fixed/Auto.
-//    - Fixed Columns (if any) will generally obtain their requested width (unless the table cannot fit them all).
-//    - Stretch Columns will share the remaining width according to their respective weight.
-//    - Mixed Fixed/Stretch columns is possible but has various side-effects on resizing behaviors.
-//      The typical use of mixing sizing policies is: any number of LEADING Fixed columns, followed by one or two TRAILING Stretch columns.
-//      (this is because the visible order of columns have subtle but necessary effects on how they react to manual resizing).
-// - When ScrollX is on:
-//    - Table defaults to ImGuiTableFlags_SizingFixedFit -> all Columns defaults to ImGuiTableColumnFlags_WidthFixed
-//    - Columns sizing policy allowed: Fixed/Auto mostly.
-//    - Fixed Columns can be enlarged as needed. Table will show a horizontal scrollbar if needed.
-//    - When using auto-resizing (non-resizable) fixed columns, querying the content width to use item right-alignment e.g. SetNextItemWidth(-FLT_MIN) doesn't make sense, would create a feedback loop.
-//    - Using Stretch columns OFTEN DOES NOT MAKE SENSE if ScrollX is on, UNLESS you have specified a value for 'inner_width' in BeginTable().
-//      If you specify a value for 'inner_width' then effectively the scrolling space is known and Stretch or mixed Fixed/Stretch columns become meaningful again.
-// - Read on documentation at the top of imgui_tables.cpp for details.

-// - You want to manipulate the open/close state of a particular sub-tree in your interface (tree node uses Int 0/1 to store their state).
-// - You want to store custom debug data easily without adding or editing structures in your code (probably not efficient, but convenient)
-// Types are NOT stored, so it is up to you to make sure your Key don't collide with different types.

-// Helper: Manually clip large list of items.
-// If you have lots evenly spaced items and you have random access to the list, you can perform coarse
-// clipping based on visibility to only submit items that are in view.
-// The clipper calculates the range of visible items and advance the cursor to compensate for the non-visible items we have skipped.
-// (Dear ImGui already clip items based on their bounds but: it needs to first layout the item to do so, and generally
-//  fetching/submitting your own data incurs additional cost. Coarse clipping using ImGuiListClipper allows you to easily
-//  scale using lists with tens of thousands of items without a problem)
-// Usage:
-//   ImGuiListClipper clipper;
-//   clipper.Begin(1000);         // We have 1000 elements, evenly spaced.
-//   while (clipper.Step())
-//       for (int i = clipper.DisplayStart; i < clipper.DisplayEnd; i++)
-//           ImGui::Text("line number %d", i);
-// Generally what happens is:
-// - Clipper lets you process the first element (DisplayStart = 0, DisplayEnd = 1) regardless of it being visible or not.
-// - User code submit that one element.
-// - Clipper can measure the height of the first element
-// - Clipper calculate the actual range of elements to display based on the current clipping rectangle, position the cursor before the first visible element.
-// - User code submit visible elements.
-// - The clipper also handles various subtleties related to keyboard/gamepad navigation, wrapping etc.

-//  - Custom graphics data needed to render the shapes needed by Dear ImGui.
-//  - Mouse cursor shapes for software cursor rendering (unless setting 'Flags |= ImFontAtlasFlags_NoMouseCursors' in the font atlas).
-// It is the user-code responsibility to setup/build the atlas, then upload the pixel data into a texture accessible by your graphics api.
-//  - Optionally, call any of the AddFont*** functions. If you don't call any, the default font embedded in the code will be loaded for you.
-//  - Call GetTexDataAsAlpha8() or GetTexDataAsRGBA32() to build and retrieve pixels data.
-//  - Upload the pixels data into a texture within your graphics system (see imgui_impl_xxxx.cpp examples)
-//  - Call SetTexID(my_tex_id); and pass the pointer/identifier to your texture in a format natural to your graphics API.
-//    This value will be passed back to you during rendering to identify the texture. Read FAQ entry about ImTextureID for more details.
-// Common pitfalls:
-// - If you pass a 'glyph_ranges' array to AddFont*** functions, you need to make sure that your array persist up until the
-//   atlas is build (when calling GetTexData*** or Build()). We only copy the pointer, not the data.
-// - Important: By default, AddFontFromMemoryTTF() takes ownership of the data. Even though we are not writing to it, we will free the pointer on destruction.
-//   You can set font_cfg->FontDataOwnedByAtlas=false to keep ownership of your data and it won't be freed,
-// - Even though many functions are suffixed with "TTF", OTF data is supported just as well.
-// - This is an old API and it is currently awkward for those and various other reasons! We will address them in the future!

-// dear imgui, v1.90.4
-// (demo code)
-
-// Help:
-// - Read FAQ at http://dearimgui.com/faq
-// - Call and read ImGui::ShowDemoWindow() in imgui_demo.cpp. All applications in examples/ are doing that.
-// - Need help integrating Dear ImGui in your codebase?
-//   - Read Getting Started https://github.com/ocornut/imgui/wiki/Getting-Started
-//   - Read 'Programmer guide' in imgui.cpp for notes on how to setup Dear ImGui in your codebase.
-// Read imgui.cpp for more details, documentation and comments.

-
-//---------------------------------------------------
-// PLEASE DO NOT REMOVE THIS FILE FROM YOUR PROJECT!
-//---------------------------------------------------
-// Message to the person tempted to delete this file when integrating Dear ImGui into their codebase:
-// Think again! It is the most useful reference code that you and other coders will want to refer to and call.
-// Have the ImGui::ShowDemoWindow() function wired in an always-available debug menu of your game/app!
-// Also include Metrics! ItemPicker! DebugLog! and other debug features.
-// Removing this file from your project is hindering access to documentation for everyone in your team,
-// likely leading you to poorer usage of the library.
-// Everything in this file will be stripped out by the linker if you don't call ImGui::ShowDemoWindow().
-// If you want to link core Dear ImGui in your shipped builds but want a thorough guarantee that the demo will not be
-// linked, you can setup your imconfig.h with #define IMGUI_DISABLE_DEMO_WINDOWS and those functions will be empty.
-// In another situation, whenever you have Dear ImGui available you probably want this to be available for reference.
-// Thank you,
-// -Your beloved friend, imgui_demo.cpp (which you won't delete)
-
-//--------------------------------------------
-// ABOUT THE MEANING OF THE 'static' KEYWORD:
-//--------------------------------------------
-// In this demo code, we frequently use 'static' variables inside functions.
-// A static variable persists across calls. It is essentially a global variable but declared inside the scope of the function.
-// Think of "static int n = 0;" as "global int n = 0;" !
-// We do this IN THE DEMO because we want:
-// - to gather code and data in the same place.
-// - to make the demo source code faster to read, faster to change, smaller in size.
-// - it is also a convenient way of storing simple UI related information as long as your function
-//   doesn't need to be reentrant or used in multiple threads.
-// This might be a pattern you will want to use in your code, but most of the data you would be working
-// with in a complex codebase is likely going to be stored outside your functions.
-
-//-----------------------------------------
-// ABOUT THE CODING STYLE OF OUR DEMO CODE
-//-----------------------------------------
-// The Demo code in this file is designed to be easy to copy-and-paste into your application!
-// Because of this:
-// - We never omit the ImGui:: prefix when calling functions, even though most code here is in the same namespace.
-// - We try to declare static variables in the local scope, as close as possible to the code using them.
-// - We never use any of the helpers/facilities used internally by Dear ImGui, unless available in the public API.
-// - We never use maths operators on ImVec2/ImVec4. For our other sources files we use them, and they are provided
-//   by imgui.h using the IMGUI_DEFINE_MATH_OPERATORS define. For your own sources file they are optional
-//   and require you either enable those, either provide your own via IM_VEC2_CLASS_EXTRA in imconfig.h.
-//   Because we can't assume anything about your support of maths operators, we cannot use them in imgui_demo.cpp.
-
-// Navigating this file:
-// - In Visual Studio: CTRL+comma ("Edit.GoToAll") can follow symbols in comments, whereas CTRL+F12 ("Edit.GoToImplementation") cannot.
-// - With Visual Assist installed: ALT+G ("VAssistX.GoToImplementation") can also follow symbols in comments.

-// dear imgui: Renderer Backend for OpenGL2 (legacy OpenGL, fixed pipeline)
-// This needs to be used along with a Platform Backend (e.g. GLFW, SDL, Win32, custom..)
-
-// Implemented features:
-//  [X] Renderer: User texture binding. Use 'GLuint' OpenGL texture identifier as void*/ImTextureID. Read the FAQ about ImTextureID!
-
-// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
-// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.
-// Learn about Dear ImGui:
-// - FAQ                  https://dearimgui.com/faq
-// - Getting Started      https://dearimgui.com/getting-started
-// - Documentation        https://dearimgui.com/docs (same as your local docs/ folder).
-// - Introduction, links and more at the top of imgui.cpp
-
-// **DO NOT USE THIS CODE IF YOUR CODE/ENGINE IS USING MODERN OPENGL (SHADERS, VBO, VAO, etc.)**
-// **Prefer using the code in imgui_impl_opengl3.cpp**
-// This code is mostly provided as a reference to learn how ImGui integration works, because it is shorter to read.
-// If your code is using GL3+ context or any semi modern OpenGL calls, using this is likely to make everything more
-// complicated, will require your code to reset every single OpenGL attributes to their initial state, and might
-// confuse your GPU driver.
-// The GL2 code is unable to reset attributes or even call e.g. "glUseProgram(0)" because they don't exist in that API.
-
-// CHANGELOG
-// (minor and older changes stripped away, please see git history for details)
-//  2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
-//  2021-12-08: OpenGL: Fixed mishandling of the ImDrawCmd::IdxOffset field! This is an old bug but it never had an effect until some internal rendering changes in 1.86.
-//  2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
-//  2021-05-19: OpenGL: Replaced direct access to ImDrawCmd::TextureId with a call to ImDrawCmd::GetTexID(). (will become a requirement)
-//  2021-01-03: OpenGL: Backup, setup and restore GL_SHADE_MODEL state, disable GL_STENCIL_TEST and disable GL_NORMAL_ARRAY client state to increase compatibility with legacy OpenGL applications.
-//  2020-01-23: OpenGL: Backup, setup and restore GL_TEXTURE_ENV to increase compatibility with legacy OpenGL applications.
-//  2019-04-30: OpenGL: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
-//  2019-02-11: OpenGL: Projecting clipping rectangles correctly using draw_data->FramebufferScale to allow multi-viewports for retina display.
-//  2018-11-30: Misc: Setting up io.BackendRendererName so it can be displayed in the About Window.
-//  2018-08-03: OpenGL: Disabling/restoring GL_LIGHTING and GL_COLOR_MATERIAL to increase compatibility with legacy OpenGL applications.
-//  2018-06-08: Misc: Extracted imgui_impl_opengl2.cpp/.h away from the old combined GLFW/SDL+OpenGL2 examples.
-//  2018-06-08: OpenGL: Use draw_data->DisplayPos and draw_data->DisplaySize to setup projection matrix and clipping rectangle.
-//  2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback and exposed ImGui_ImplOpenGL2_RenderDrawData() in the .h file so you can call it yourself.
-//  2017-09-01: OpenGL: Save and restore current polygon mode.
-//  2016-09-10: OpenGL: Uploading font texture as RGBA32 to increase compatibility with users shaders (not ideal).
-//  2016-09-05: OpenGL: Fixed save and restore of current scissor rectangle.

-// dear imgui: Renderer Backend for modern OpenGL with shaders / programmatic pipeline
-// - Desktop GL: 2.x 3.x 4.x
-// - Embedded GL: ES 2.0 (WebGL 1.0), ES 3.0 (WebGL 2.0)
-// This needs to be used along with a Platform Backend (e.g. GLFW, SDL, Win32, custom..)
-
-// Implemented features:
-//  [X] Renderer: User texture binding. Use 'GLuint' OpenGL texture identifier as void*/ImTextureID. Read the FAQ about ImTextureID!
-//  [x] Renderer: Large meshes support (64k+ vertices) with 16-bit indices (Desktop OpenGL only).
-
-// About WebGL/ES:
-// - You need to '#define IMGUI_IMPL_OPENGL_ES2' or '#define IMGUI_IMPL_OPENGL_ES3' to use WebGL or OpenGL ES.
-// - This is done automatically on iOS, Android and Emscripten targets.
-// - For other targets, the define needs to be visible from the imgui_impl_opengl3.cpp compilation unit. If unsure, define globally or in imconfig.h.
-
-// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
-// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.
-// Learn about Dear ImGui:
-// - FAQ                  https://dearimgui.com/faq
-// - Getting Started      https://dearimgui.com/getting-started
-// - Documentation        https://dearimgui.com/docs (same as your local docs/ folder).
-// - Introduction, links and more at the top of imgui.cpp
-
-// About GLSL version:
-//  The 'glsl_version' initialization parameter should be nullptr (default) or a "#version XXX" string.
-//  On computer platform the GLSL version default to "#version 130". On OpenGL ES 3 platform it defaults to "#version 300 es"
-//  Only override if your GL version doesn't handle this GLSL version. See GLSL version table at the top of imgui_impl_opengl3.cpp.

-//-----------------------------------------------------------------------------
-// About imgui_impl_opengl3_loader.h:
-//
-// We embed our own OpenGL loader to not require user to provide their own or to have to use ours,
-// which proved to be endless problems for users.
-// Our loader is custom-generated, based on gl3w but automatically filtered to only include
-// enums/functions that we use in our imgui_impl_opengl3.cpp source file in order to be small.
-//
-// YOU SHOULD NOT NEED TO INCLUDE/USE THIS DIRECTLY. THIS IS USED BY imgui_impl_opengl3.cpp ONLY.
-// THE REST OF YOUR APP SHOULD USE A DIFFERENT GL LOADER: ANY GL LOADER OF YOUR CHOICE.
-//
-// IF YOU GET BUILD ERRORS IN THIS FILE (commonly macro redefinitions or function redefinitions):
-// IT LIKELY MEANS THAT YOU ARE BUILDING 'imgui_impl_opengl3.cpp' OR INCUDING 'imgui_impl_opengl3_loader.h'
-// IN THE SAME COMPILATION UNIT AS ONE OF YOUR FILE WHICH IS USING A THIRD-PARTY OPENGL LOADER.
-// (e.g. COULD HAPPEN IF YOU ARE DOING A UNITY/JUMBO BUILD, OR INCLUDING .CPP FILES FROM OTHERS)
-// YOU SHOULD NOT BUILD BOTH IN THE SAME COMPILATION UNIT.
-// BUT IF YOU REALLY WANT TO, you can '#define IMGUI_IMPL_OPENGL_LOADER_CUSTOM' and imgui_impl_opengl3.cpp
-// WILL NOT BE USING OUR LOADER, AND INSTEAD EXPECT ANOTHER/YOUR LOADER TO BE AVAILABLE IN THE COMPILATION UNIT.
-//

-//   python gl3w_gen.py --output ../imgui/backends/imgui_impl_opengl3_loader.h --ref ../imgui/backends/imgui_impl_opengl3.cpp ./extra_symbols.txt

-// dear imgui: Platform Backend for SDL2
-// This needs to be used along with a Renderer (e.g. DirectX11, OpenGL3, Vulkan..)
-// (Info: SDL2 is a cross-platform general purpose library for handling windows, inputs, graphics context creation, etc.)
-// (Prefer SDL 2.0.5+ for full feature support.)
-
-// Implemented features:
-//  [X] Platform: Clipboard support.
-//  [X] Platform: Mouse support. Can discriminate Mouse/TouchScreen.
-//  [X] Platform: Keyboard support. Since 1.87 we are using the io.AddKeyEvent() function. Pass ImGuiKey values to all key functions e.g. ImGui::IsKeyPressed(ImGuiKey_Space). [Legacy SDL_SCANCODE_* values will also be supported unless IMGUI_DISABLE_OBSOLETE_KEYIO is set]
-//  [X] Platform: Gamepad support. Enabled with 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad'.
-//  [X] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'.
-//  [X] Platform: Basic IME support. App needs to call 'SDL_SetHint(SDL_HINT_IME_SHOW_UI, "1");' before SDL_CreateWindow()!.
-
-// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
-// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.
-// Learn about Dear ImGui:
-// - FAQ                  https://dearimgui.com/faq
-// - Getting Started      https://dearimgui.com/getting-started
-// - Documentation        https://dearimgui.com/docs (same as your local docs/ folder).

-
-// CHANGELOG
-// (minor and older changes stripped away, please see git history for details)
-//  2024-02-14: Inputs: Handle gamepad disconnection. Added ImGui_ImplSDL2_SetGamepadMode().
-//  2023-10-05: Inputs: Added support for extra ImGuiKey values: F13 to F24 function keys, app back/forward keys.
-//  2023-04-06: Inputs: Avoid calling SDL_StartTextInput()/SDL_StopTextInput() as they don't only pertain to IME. It's unclear exactly what their relation is to IME. (#6306)
-//  2023-04-04: Inputs: Added support for io.AddMouseSourceEvent() to discriminate ImGuiMouseSource_Mouse/ImGuiMouseSource_TouchScreen. (#2702)
-//  2023-02-23: Accept SDL_GetPerformanceCounter() not returning a monotonically increasing value. (#6189, #6114, #3644)
-//  2023-02-07: Implement IME handler (io.SetPlatformImeDataFn will call SDL_SetTextInputRect()/SDL_StartTextInput()).
-//  2023-02-07: *BREAKING CHANGE* Renamed this backend file from imgui_impl_sdl.cpp/.h to imgui_impl_sdl2.cpp/.h in prevision for the future release of SDL3.
-//  2023-02-02: Avoid calling SDL_SetCursor() when cursor has not changed, as the function is surprisingly costly on Mac with latest SDL (may be fixed in next SDL version).
-//  2023-02-02: Added support for SDL 2.0.18+ preciseX/preciseY mouse wheel data for smooth scrolling + Scaling X value on Emscripten (bug?). (#4019, #6096)
-//  2023-02-02: Removed SDL_MOUSEWHEEL value clamping, as values seem correct in latest Emscripten. (#4019)
-//  2023-02-01: Flipping SDL_MOUSEWHEEL 'wheel.x' value to match other backends and offer consistent horizontal scrolling direction. (#4019, #6096, #1463)
-//  2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
-//  2022-09-26: Inputs: Disable SDL 2.0.22 new "auto capture" (SDL_HINT_MOUSE_AUTO_CAPTURE) which prevents drag and drop across windows for multi-viewport support + don't capture when drag and dropping. (#5710)
-//  2022-09-26: Inputs: Renamed ImGuiKey_ModXXX introduced in 1.87 to ImGuiMod_XXX (old names still supported).
-//  2022-03-22: Inputs: Fix mouse position issues when dragging outside of boundaries. SDL_CaptureMouse() erroneously still gives out LEAVE events when hovering OS decorations.
-//  2022-03-22: Inputs: Added support for extra mouse buttons (SDL_BUTTON_X1/SDL_BUTTON_X2).
-//  2022-02-04: Added SDL_Renderer* parameter to ImGui_ImplSDL2_InitForSDLRenderer(), so we can use SDL_GetRendererOutputSize() instead of SDL_GL_GetDrawableSize() when bound to a SDL_Renderer.
-//  2022-01-26: Inputs: replaced short-lived io.AddKeyModsEvent() (added two weeks ago) with io.AddKeyEvent() using ImGuiKey_ModXXX flags. Sorry for the confusion.
-//  2021-01-20: Inputs: calling new io.AddKeyAnalogEvent() for gamepad support, instead of writing directly to io.NavInputs[].
-//  2022-01-17: Inputs: calling new io.AddMousePosEvent(), io.AddMouseButtonEvent(), io.AddMouseWheelEvent() API (1.87+).
-//  2022-01-17: Inputs: always update key mods next and before key event (not in NewFrame) to fix input queue with very low framerates.
-//  2022-01-12: Update mouse inputs using SDL_MOUSEMOTION/SDL_WINDOWEVENT_LEAVE + fallback to provide it when focused but not hovered/captured. More standard and will allow us to pass it to future input queue API.
-//  2022-01-12: Maintain our own copy of MouseButtonsDown mask instead of using ImGui::IsAnyMouseDown() which will be obsoleted.
-//  2022-01-10: Inputs: calling new io.AddKeyEvent(), io.AddKeyModsEvent() + io.SetKeyEventNativeData() API (1.87+). Support for full ImGuiKey range.
-//  2021-08-17: Calling io.AddFocusEvent() on SDL_WINDOWEVENT_FOCUS_GAINED/SDL_WINDOWEVENT_FOCUS_LOST.
-//  2021-07-29: Inputs: MousePos is correctly reported when the host platform window is hovered but not focused (using SDL_GetMouseFocus() + SDL_HINT_MOUSE_FOCUS_CLICKTHROUGH, requires SDL 2.0.5+)
-//  2021-06-29: *BREAKING CHANGE* Removed 'SDL_Window* window' parameter to ImGui_ImplSDL2_NewFrame() which was unnecessary.
-//  2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
-//  2021-03-22: Rework global mouse pos availability check listing supported platforms explicitly, effectively fixing mouse access on Raspberry Pi. (#2837, #3950)
-//  2020-05-25: Misc: Report a zero display-size when window is minimized, to be consistent with other backends.
-//  2020-02-20: Inputs: Fixed mapping for ImGuiKey_KeyPadEnter (using SDL_SCANCODE_KP_ENTER instead of SDL_SCANCODE_RETURN2).
-//  2019-12-17: Inputs: On Wayland, use SDL_GetMouseState (because there is no global mouse state).
-//  2019-12-05: Inputs: Added support for ImGuiMouseCursor_NotAllowed mouse cursor.
-//  2019-07-21: Inputs: Added mapping for ImGuiKey_KeyPadEnter.
-//  2019-04-23: Inputs: Added support for SDL_GameController (if ImGuiConfigFlags_NavEnableGamepad is set by user application).
-//  2019-03-12: Misc: Preserve DisplayFramebufferScale when main window is minimized.
-//  2018-12-21: Inputs: Workaround for Android/iOS which don't seem to handle focus related calls.
-//  2018-11-30: Misc: Setting up io.BackendPlatformName so it can be displayed in the About Window.
-//  2018-11-14: Changed the signature of ImGui_ImplSDL2_ProcessEvent() to take a 'const SDL_Event*'.
-//  2018-08-01: Inputs: Workaround for Emscripten which doesn't seem to handle focus related calls.
-//  2018-06-29: Inputs: Added support for the ImGuiMouseCursor_Hand cursor.
-//  2018-06-08: Misc: Extracted imgui_impl_sdl.cpp/.h away from the old combined SDL2+OpenGL/Vulkan examples.
-//  2018-06-08: Misc: ImGui_ImplSDL2_InitForOpenGL() now takes a SDL_GLContext parameter.
-//  2018-05-09: Misc: Fixed clipboard paste memory leak (we didn't call SDL_FreeMemory on the data returned by SDL_GetClipboardText).
-//  2018-03-20: Misc: Setup io.BackendFlags ImGuiBackendFlags_HasMouseCursors flag + honor ImGuiConfigFlags_NoMouseCursorChange flag.
-//  2018-02-16: Inputs: Added support for mouse cursors, honoring ImGui::GetMouseCursor() value.
-//  2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.
-//  2018-02-06: Inputs: Added mapping for ImGuiKey_Space.
-//  2018-02-05: Misc: Using SDL_GetPerformanceCounter() instead of SDL_GetTicks() to be able to handle very high framerate (1000+ FPS).
-//  2018-02-05: Inputs: Keyboard mapping is using scancodes everywhere instead of a confusing mixture of keycodes and scancodes.
-//  2018-01-20: Inputs: Added Horizontal Mouse Wheel support.
-//  2018-01-19: Inputs: When available (SDL 2.0.4+) using SDL_CaptureMouse() to retrieve coordinates outside of client area when dragging. Otherwise (SDL 2.0.3 and before) testing for SDL_WINDOW_INPUT_FOCUS instead of SDL_WINDOW_MOUSE_FOCUS.
-//  2018-01-18: Inputs: Added mapping for ImGuiKey_Insert.
-//  2017-08-25: Inputs: MousePos set to -FLT_MAX,-FLT_MAX when mouse is unavailable/missing (instead of -1,-1).
-//  2016-10-15: Misc: Added a void* user_data parameter to Clipboard function handlers.

-// dear imgui: Platform Backend for SDL2
-// This needs to be used along with a Renderer (e.g. DirectX11, OpenGL3, Vulkan..)
-// (Info: SDL2 is a cross-platform general purpose library for handling windows, inputs, graphics context creation, etc.)
-
-// Implemented features:
-//  [X] Platform: Clipboard support.
-//  [X] Platform: Mouse support. Can discriminate Mouse/TouchScreen.
-//  [X] Platform: Keyboard support. Since 1.87 we are using the io.AddKeyEvent() function. Pass ImGuiKey values to all key functions e.g. ImGui::IsKeyPressed(ImGuiKey_Space). [Legacy SDL_SCANCODE_* values will also be supported unless IMGUI_DISABLE_OBSOLETE_KEYIO is set]
-//  [X] Platform: Gamepad support. Enabled with 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad'.
-//  [X] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'.
-//  [X] Platform: Basic IME support. App needs to call 'SDL_SetHint(SDL_HINT_IME_SHOW_UI, "1");' before SDL_CreateWindow()!.
-
-// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
-// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.

-    // - Input queries can then read input by specifying ImGuiKeyOwner_Any (== 0), ImGuiKeyOwner_None (== -1) or a custom ID.
-    // - Legacy input queries (without specifying an owner or _Any or _None) are equivalent to using ImGuiKeyOwner_Any (== 0).
-    // - Input ownership is automatically released on the frame after a key is released. Therefore:
-    //   - for ownership registration happening as a result of a down/press event, the SetKeyOwner() call may be done once (common case).
-    //   - for ownership registration happening ahead of a down/press event, the SetKeyOwner() call needs to be made every frame (happens if e.g. claiming ownership on hover).
-    // - SetItemKeyOwner() is a shortcut for common simple case. A custom widget will probably want to call SetKeyOwner() multiple times directly based on its interaction state.
-    // - This is marked experimental because not all widgets are fully honoring the Set/Test idioms. We will need to move forward step by step.

-// Typical tables call flow: (root level is generally public API):
-//-----------------------------------------------------------------------------
-// - BeginTable()                               user begin into a table
-//    | BeginChild()                            - (if ScrollX/ScrollY is set)
-//    | TableBeginInitMemory()                  - first time table is used
-//    | TableResetSettings()                    - on settings reset
-//    | TableLoadSettings()                     - on settings load
-//    | TableBeginApplyRequests()               - apply queued resizing/reordering/hiding requests
-//    | - TableSetColumnWidth()                 - apply resizing width (for mouse resize, often requested by previous frame)
-//    |    - TableUpdateColumnsWeightFromWidth()- recompute columns weights (of stretch columns) from their respective width
-// - TableSetupColumn()                         user submit columns details (optional)
-// - TableSetupScrollFreeze()                   user submit scroll freeze information (optional)
-//-----------------------------------------------------------------------------
-// - TableUpdateLayout() [Internal]             followup to BeginTable(): setup everything: widths, columns positions, clipping rectangles. Automatically called by the FIRST call to TableNextRow() or TableHeadersRow().
-//    | TableSetupDrawChannels()                - setup ImDrawList channels
-//    | TableUpdateBorders()                    - detect hovering columns for resize, ahead of contents submission
-//    | TableBeginContextMenuPopup()
-//    | - TableDrawDefaultContextMenu()         - draw right-click context menu contents
-//-----------------------------------------------------------------------------
-// - TableHeadersRow() or TableHeader()         user submit a headers row (optional)
-//    | TableSortSpecsClickColumn()             - when left-clicked: alter sort order and sort direction
-//    | TableOpenContextMenu()                  - when right-clicked: trigger opening of the default context menu
-// - TableGetSortSpecs()                        user queries updated sort specs (optional, generally after submitting headers)
-// - TableNextRow()                             user begin into a new row (also automatically called by TableHeadersRow())
-//    | TableEndRow()                           - finish existing row
-//    | TableBeginRow()                         - add a new row
-// - TableSetColumnIndex() / TableNextColumn()  user begin into a cell
-//    | TableEndCell()                          - close existing column/cell
-//    | TableBeginCell()                        - enter into current column/cell
-// - [...]                                      user emit contents
-//-----------------------------------------------------------------------------
-// - EndTable()                                 user ends the table
-//    | TableDrawBorders()                      - draw outer borders, inner vertical borders
-//    | TableMergeDrawChannels()                - merge draw channels if clipping isn't required
-//    | EndChild()                              - (if ScrollX/ScrollY is set)

-// TABLE SIZING
-//-----------------------------------------------------------------------------
-// (Read carefully because this is subtle but it does make sense!)
-//-----------------------------------------------------------------------------
-// About 'outer_size':
-// Its meaning needs to differ slightly depending on if we are using ScrollX/ScrollY flags.
-// Default value is ImVec2(0.0f, 0.0f).
-//   X
-//   - outer_size.x <= 0.0f  ->  Right-align from window/work-rect right-most edge. With -FLT_MIN or 0.0f will align exactly on right-most edge.
-//   - outer_size.x  > 0.0f  ->  Set Fixed width.
-//   Y with ScrollX/ScrollY disabled: we output table directly in current window
-//   - outer_size.y  < 0.0f  ->  Bottom-align (but will auto extend, unless _NoHostExtendY is set). Not meaningful if parent window can vertically scroll.
-//   - outer_size.y  = 0.0f  ->  No minimum height (but will auto extend, unless _NoHostExtendY is set)
-//   - outer_size.y  > 0.0f  ->  Set Minimum height (but will auto extend, unless _NoHostExtendY is set)
-//   Y with ScrollX/ScrollY enabled: using a child window for scrolling
-//   - outer_size.y  < 0.0f  ->  Bottom-align. Not meaningful if parent window can vertically scroll.
-//   - outer_size.y  = 0.0f  ->  Bottom-align, consistent with BeginChild(). Not recommended unless table is last item in parent window.
-//   - outer_size.y  > 0.0f  ->  Set Exact height. Recommended when using Scrolling on any axis.
-//-----------------------------------------------------------------------------
-// Outer size is also affected by the NoHostExtendX/NoHostExtendY flags.
-// Important to note how the two flags have slightly different behaviors!
-//   - ImGuiTableFlags_NoHostExtendX -> Make outer width auto-fit to columns (overriding outer_size.x value). Only available when ScrollX/ScrollY are disabled and Stretch columns are not used.
-//   - ImGuiTableFlags_NoHostExtendY -> Make outer height stop exactly at outer_size.y (prevent auto-extending table past the limit). Only available when ScrollX/ScrollY is disabled. Data below the limit will be clipped and not visible.
-// In theory ImGuiTableFlags_NoHostExtendY could be the default and any non-scrolling tables with outer_size.y != 0.0f would use exact height.
-// This would be consistent but perhaps less useful and more confusing (as vertically clipped items are not useful and not easily noticeable).
-//-----------------------------------------------------------------------------
-// About 'inner_width':
-//   With ScrollX disabled:
-//   - inner_width          ->  *ignored*
-//   With ScrollX enabled:
-//   - inner_width  < 0.0f  ->  *illegal* fit in known width (right align from outer_size.x) <-- weird
-//   - inner_width  = 0.0f  ->  fit in outer_width: Fixed size columns will take space they need (if avail, otherwise shrink down), Stretch columns becomes Fixed columns.
-//   - inner_width  > 0.0f  ->  override scrolling width, generally to be larger than outer_size.x. Fixed column take space they need (if avail, otherwise shrink down), Stretch columns share remaining space!
-//-----------------------------------------------------------------------------
-// Details:
-// - If you want to use Stretch columns with ScrollX, you generally need to specify 'inner_width' otherwise the concept
-//   of "available space" doesn't make sense.
-// - Even if not really useful, we allow 'inner_width < outer_size.x' for consistency and to facilitate understanding
-//   of what the value does.
-//-----------------------------------------------------------------------------
-
-//-----------------------------------------------------------------------------
-// COLUMNS SIZING POLICIES
-// (Reference: ImGuiTableFlags_SizingXXX flags and ImGuiTableColumnFlags_WidthXXX flags)
-//-----------------------------------------------------------------------------
-// About overriding column sizing policy and width/weight with TableSetupColumn():
-// We use a default parameter of -1 for 'init_width'/'init_weight'.
-//   - with ImGuiTableColumnFlags_WidthFixed,    init_width  <= 0 (default)  --> width is automatic
-//   - with ImGuiTableColumnFlags_WidthFixed,    init_width  >  0 (explicit) --> width is custom
-//   - with ImGuiTableColumnFlags_WidthStretch,  init_weight <= 0 (default)  --> weight is 1.0f
-//   - with ImGuiTableColumnFlags_WidthStretch,  init_weight >  0 (explicit) --> weight is custom
-// Widths are specified _without_ CellPadding. If you specify a width of 100.0f, the column will be cover (100.0f + Padding * 2.0f)
-// and you can fit a 100.0f wide item in it without clipping and with padding honored.
-//-----------------------------------------------------------------------------
-// About default sizing policy (if you don't specify a ImGuiTableColumnFlags_WidthXXXX flag)
-//   - with Table policy ImGuiTableFlags_SizingFixedFit      --> default Column policy is ImGuiTableColumnFlags_WidthFixed, default Width is equal to contents width
-//   - with Table policy ImGuiTableFlags_SizingFixedSame     --> default Column policy is ImGuiTableColumnFlags_WidthFixed, default Width is max of all contents width
-//   - with Table policy ImGuiTableFlags_SizingStretchSame   --> default Column policy is ImGuiTableColumnFlags_WidthStretch, default Weight is 1.0f
-//   - with Table policy ImGuiTableFlags_SizingStretchWeight --> default Column policy is ImGuiTableColumnFlags_WidthStretch, default Weight is proportional to contents
-// Default Width and default Weight can be overridden when calling TableSetupColumn().
-//-----------------------------------------------------------------------------
-// About mixing Fixed/Auto and Stretch columns together:
-//   - the typical use of mixing sizing policies is: any number of LEADING Fixed columns, followed by one or two TRAILING Stretch columns.
-//   - using mixed policies with ScrollX does not make much sense, as using Stretch columns with ScrollX does not make much sense in the first place!
-//     that is, unless 'inner_width' is passed to BeginTable() to explicitly provide a total width to layout columns in.
-//   - when using ImGuiTableFlags_SizingFixedSame with mixed columns, only the Fixed/Auto columns will match their widths to the width of the maximum contents.
-//   - when using ImGuiTableFlags_SizingStretchSame with mixed columns, only the Stretch columns will match their weights/widths.
-//-----------------------------------------------------------------------------
-// About using column width:
-// If a column is manually resizable or has a width specified with TableSetupColumn():
-//   - you may use GetContentRegionAvail().x to query the width available in a given column.
-//   - right-side alignment features such as SetNextItemWidth(-x) or PushItemWidth(-x) will rely on this width.
-// If the column is not resizable and has no width specified with TableSetupColumn():
-//   - its width will be automatic and be set to the max of items submitted.
-//   - therefore you generally cannot have ALL items of the columns use e.g. SetNextItemWidth(-FLT_MIN).
-//   - but if the column has one or more items of known/fixed size, this will become the reference width used by SetNextItemWidth(-FLT_MIN).

-// TABLES CLIPPING/CULLING
-//-----------------------------------------------------------------------------
-// About clipping/culling of Rows in Tables:
-// - For large numbers of rows, it is recommended you use ImGuiListClipper to submit only visible rows.
-//   ImGuiListClipper is reliant on the fact that rows are of equal height.
-//   See 'Demo->Tables->Vertical Scrolling' or 'Demo->Tables->Advanced' for a demo of using the clipper.
-// - Note that auto-resizing columns don't play well with using the clipper.
-//   By default a table with _ScrollX but without _Resizable will have column auto-resize.
-//   So, if you want to use the clipper, make sure to either enable _Resizable, either setup columns width explicitly with _WidthFixed.
-//-----------------------------------------------------------------------------
-// About clipping/culling of Columns in Tables:
-// - Both TableSetColumnIndex() and TableNextColumn() return true when the column is visible or performing
-//   width measurements. Otherwise, you may skip submitting the contents of a cell/column, BUT ONLY if you know
-//   it is not going to contribute to row height.
-//   In many situations, you may skip submitting contents for every column but one (e.g. the first one).
-// - Case A: column is not hidden by user, and at least partially in sight (most common case).
-// - Case B: column is clipped / out of sight (because of scrolling or parent ClipRect): TableNextColumn() return false as a hint but we still allow layout output.
-// - Case C: column is hidden explicitly by the user (e.g. via the context menu, or _DefaultHide column flag, etc.).
-//
-//                        [A]         [B]          [C]
-//  TableNextColumn():    true        false        false       -> [userland] when TableNextColumn() / TableSetColumnIndex() returns false, user can skip submitting items but only if the column doesn't contribute to row height.
-//          SkipItems:    false       false        true        -> [internal] when SkipItems is true, most widgets will early out if submitted, resulting is no layout output.
-//           ClipRect:    normal      zero-width   zero-width  -> [internal] when ClipRect is zero, ItemAdd() will return false and most widgets will early out mid-way.
-//  ImDrawList output:    normal      dummy        dummy       -> [internal] when using the dummy channel, ImDrawList submissions (if any) will be wasted (because cliprect is zero-width anyway).
-//
-// - We need to distinguish those cases because non-hidden columns that are clipped outside of scrolling bounds should still contribute their height to the row.
-//   However, in the majority of cases, the contribution to row height is the same for all columns, or the tallest cells are known by the programmer.
-//-----------------------------------------------------------------------------
-// About clipping/culling of whole Tables:
-// - Scrolling tables with a known outer size can be clipped earlier as BeginTable() will return false.

-// stb_rect_pack.h - v1.01 - public domain - rectangle packing
-// Sean Barrett 2014
-//
-// Useful for e.g. packing rectangular textures into an atlas.
-// Does not do rotation.
-//
-// Before #including,
-//
-//    #define STB_RECT_PACK_IMPLEMENTATION
-//
-// in the file that you want to have the implementation.
-//
-// Not necessarily the awesomest packing method, but better than
-// the totally naive one in stb_truetype (which is primarily what
-// this is meant to replace).
-//
-// Has only had a few tests run, may have issues.
-//
-// More docs to come.
-//
-// No memory allocations; uses qsort() and assert() from stdlib.
-// Can override those by defining STBRP_SORT and STBRP_ASSERT.
-//
-// This library currently uses the Skyline Bottom-Left algorithm.
-//
-// Please note: better rectangle packers are welcome! Please
-// implement them to the same API, but with a different init
-// function.

-// [DEAR IMGUI]
-// This is a slightly modified version of stb_textedit.h 1.14.
-// Those changes would need to be pushed into nothings/stb:
-// - Fix in stb_textedit_discard_redo (see https://github.com/nothings/stb/issues/321)
-// - Fix in stb_textedit_find_charpos to handle last line (see https://github.com/ocornut/imgui/issues/6000 + #6783)
-// Grep for [DEAR IMGUI] to find the changes.
-// - Also renamed macros used or defined outside of IMSTB_TEXTEDIT_IMPLEMENTATION block from STB_TEXTEDIT_* to IMSTB_TEXTEDIT_*
-
-// stb_textedit.h - v1.14  - public domain - Sean Barrett
-// Development of this library was sponsored by RAD Game Tools
-//
-// This C header file implements the guts of a multi-line text-editing
-// widget; you implement display, word-wrapping, and low-level string
-// insertion/deletion, and stb_textedit will map user inputs into
-// insertions & deletions, plus updates to the cursor position,
-// selection state, and undo state.
-//
-// It is intended for use in games and other systems that need to build
-// their own custom widgets and which do not have heavy text-editing
-// requirements (this library is not recommended for use for editing large
-// texts, as its performance does not scale and it has limited undo).
-//
-// Non-trivial behaviors are modelled after Windows text controls.
-//
-//
-// LICENSE
-//
-// See end of file for license information.
-//
-//
-// DEPENDENCIES
-//
-// Uses the C runtime function 'memmove', which you can override
-// by defining IMSTB_TEXTEDIT_memmove before the implementation.
-// Uses no other functions. Performs no runtime allocations.
-//

-//   it will operate in "header file" mode. In this mode, it declares a
-//   single public symbol, STB_TexteditState, which encapsulates the current
-//   state of a text widget (except for the string, which you will store
-//   separately).
-//
-//   To compile in this mode, you must define STB_TEXTEDIT_CHARTYPE to a
-//   primitive type that defines a single character (e.g. char, wchar_t, etc).
-//
-//   To save space or increase undo-ability, you can optionally define the
-//   following things that are used by the undo system:
-//
-//      STB_TEXTEDIT_POSITIONTYPE         small int type encoding a valid cursor position
-//      STB_TEXTEDIT_UNDOSTATECOUNT       the number of undo states to allow
-//      STB_TEXTEDIT_UNDOCHARCOUNT        the number of characters to store in the undo buffer
-//
-//   If you don't define these, they are set to permissive types and
-//   moderate sizes. The undo system does no memory allocations, so
-//   it grows STB_TexteditState by the worst-case storage which is (in bytes):
-//
-//        [4 + 3 * sizeof(STB_TEXTEDIT_POSITIONTYPE)] * STB_TEXTEDIT_UNDOSTATECOUNT
-//      +          sizeof(STB_TEXTEDIT_CHARTYPE)      * STB_TEXTEDIT_UNDOCHARCOUNT
-//
-//
-// Implementation mode:
-//
-//   If you define STB_TEXTEDIT_IMPLEMENTATION before including this, it
-//   will compile the implementation of the text edit widget, depending
-//   on a large number of symbols which must be defined before the include.
-//
-//   The implementation is defined only as static functions. You will then
-//   need to provide your own APIs in the same file which will access the
-//   static functions.
-//
-//   The basic concept is that you provide a "string" object which
-//   behaves like an array of characters. stb_textedit uses indices to
-//   refer to positions in the string, implicitly representing positions
-//   in the displayed textedit. This is true for both plain text and
-//   rich text; even with rich text stb_truetype interacts with your
-//   code as if there was an array of all the displayed characters.
-//
-// Symbols that must be the same in header-file and implementation mode:
-//
-//     STB_TEXTEDIT_CHARTYPE             the character type
-//     STB_TEXTEDIT_POSITIONTYPE         small type that is a valid cursor position
-//     STB_TEXTEDIT_UNDOSTATECOUNT       the number of undo states to allow
-//     STB_TEXTEDIT_UNDOCHARCOUNT        the number of characters to store in the undo buffer
-//
-// Symbols you must define for implementation mode:
-//
-//    STB_TEXTEDIT_STRING               the type of object representing a string being edited,
-//                                      typically this is a wrapper object with other data you need
-//
-//    STB_TEXTEDIT_STRINGLEN(obj)       the length of the string (ideally O(1))
-//    STB_TEXTEDIT_LAYOUTROW(&r,obj,n)  returns the results of laying out a line of characters
-//                                        starting from character #n (see discussion below)
-//    STB_TEXTEDIT_GETWIDTH(obj,n,i)    returns the pixel delta from the xpos of the i'th character
-//                                        to the xpos of the i+1'th char for a line of characters
-//                                        starting at character #n (i.e. accounts for kerning
-//                                        with previous char)
-//    STB_TEXTEDIT_KEYTOTEXT(k)         maps a keyboard input to an insertable character
-//                                        (return type is int, -1 means not valid to insert)
-//    STB_TEXTEDIT_GETCHAR(obj,i)       returns the i'th character of obj, 0-based
-//    STB_TEXTEDIT_NEWLINE              the character returned by _GETCHAR() we recognize
-//                                        as manually wordwrapping for end-of-line positioning
-//
-//    STB_TEXTEDIT_DELETECHARS(obj,i,n)      delete n characters starting at i
-//    STB_TEXTEDIT_INSERTCHARS(obj,i,c*,n)   insert n characters at i (pointed to by STB_TEXTEDIT_CHARTYPE*)
-//
-//    STB_TEXTEDIT_K_SHIFT       a power of two that is or'd in to a keyboard input to represent the shift key
-//
-//    STB_TEXTEDIT_K_LEFT        keyboard input to move cursor left
-//    STB_TEXTEDIT_K_RIGHT       keyboard input to move cursor right
-//    STB_TEXTEDIT_K_UP          keyboard input to move cursor up
-//    STB_TEXTEDIT_K_DOWN        keyboard input to move cursor down
-//    STB_TEXTEDIT_K_PGUP        keyboard input to move cursor up a page
-//    STB_TEXTEDIT_K_PGDOWN      keyboard input to move cursor down a page
-//    STB_TEXTEDIT_K_LINESTART   keyboard input to move cursor to start of line  // e.g. HOME
-//    STB_TEXTEDIT_K_LINEEND     keyboard input to move cursor to end of line    // e.g. END
-//    STB_TEXTEDIT_K_TEXTSTART   keyboard input to move cursor to start of text  // e.g. ctrl-HOME
-//    STB_TEXTEDIT_K_TEXTEND     keyboard input to move cursor to end of text    // e.g. ctrl-END
-//    STB_TEXTEDIT_K_DELETE      keyboard input to delete selection or character under cursor
-//    STB_TEXTEDIT_K_BACKSPACE   keyboard input to delete selection or character left of cursor
-//    STB_TEXTEDIT_K_UNDO        keyboard input to perform undo
-//    STB_TEXTEDIT_K_REDO        keyboard input to perform redo
-//
-// Optional:
-//    STB_TEXTEDIT_K_INSERT              keyboard input to toggle insert mode
-//    STB_TEXTEDIT_IS_SPACE(ch)          true if character is whitespace (e.g. 'isspace'),
-//                                          required for default WORDLEFT/WORDRIGHT handlers
-//    STB_TEXTEDIT_MOVEWORDLEFT(obj,i)   custom handler for WORDLEFT, returns index to move cursor to
-//    STB_TEXTEDIT_MOVEWORDRIGHT(obj,i)  custom handler for WORDRIGHT, returns index to move cursor to
-//    STB_TEXTEDIT_K_WORDLEFT            keyboard input to move cursor left one word // e.g. ctrl-LEFT
-//    STB_TEXTEDIT_K_WORDRIGHT           keyboard input to move cursor right one word // e.g. ctrl-RIGHT
-//    STB_TEXTEDIT_K_LINESTART2          secondary keyboard input to move cursor to start of line
-//    STB_TEXTEDIT_K_LINEEND2            secondary keyboard input to move cursor to end of line
-//    STB_TEXTEDIT_K_TEXTSTART2          secondary keyboard input to move cursor to start of text
-//    STB_TEXTEDIT_K_TEXTEND2            secondary keyboard input to move cursor to end of text
-//
-// Keyboard input must be encoded as a single integer value; e.g. a character code
-// and some bitflags that represent shift states. to simplify the interface, SHIFT must
-// be a bitflag, so we can test the shifted state of cursor movements to allow selection,
-// i.e. (STB_TEXTEDIT_K_RIGHT|STB_TEXTEDIT_K_SHIFT) should be shifted right-arrow.
-//
-// You can encode other things, such as CONTROL or ALT, in additional bits, and
-// then test for their presence in e.g. STB_TEXTEDIT_K_WORDLEFT. For example,
-// my Windows implementations add an additional CONTROL bit, and an additional KEYDOWN
-// bit. Then all of the STB_TEXTEDIT_K_ values bitwise-or in the KEYDOWN bit,
-// and I pass both WM_KEYDOWN and WM_CHAR events to the "key" function in the
-// API below. The control keys will only match WM_KEYDOWN events because of the
-// keydown bit I add, and STB_TEXTEDIT_KEYTOTEXT only tests for the KEYDOWN
-// bit so it only decodes WM_CHAR events.
-//
-// STB_TEXTEDIT_LAYOUTROW returns information about the shape of one displayed
-// row of characters assuming they start on the i'th character--the width and
-// the height and the number of characters consumed. This allows this library
-// to traverse the entire layout incrementally. You need to compute word-wrapping
-// here.
-//
-// Each textfield keeps its own insert mode state, which is not how normal
-// applications work. To keep an app-wide insert mode, update/copy the
-// "insert_mode" field of STB_TexteditState before/after calling API functions.
-//
-// API
-//
-//    void stb_textedit_initialize_state(STB_TexteditState *state, int is_single_line)
-//
-//    void stb_textedit_click(STB_TEXTEDIT_STRING *str, STB_TexteditState *state, float x, float y)
-//    void stb_textedit_drag(STB_TEXTEDIT_STRING *str, STB_TexteditState *state, float x, float y)
-//    int  stb_textedit_cut(STB_TEXTEDIT_STRING *str, STB_TexteditState *state)
-//    int  stb_textedit_paste(STB_TEXTEDIT_STRING *str, STB_TexteditState *state, STB_TEXTEDIT_CHARTYPE *text, int len)
-//    void stb_textedit_key(STB_TEXTEDIT_STRING *str, STB_TexteditState *state, STB_TEXEDIT_KEYTYPE key)
-//
-//    Each of these functions potentially updates the string and updates the
-//    state.
-//
-//      initialize_state:
-//          set the textedit state to a known good default state when initially
-//          constructing the textedit.
-//
-//      click:
-//          call this with the mouse x,y on a mouse down; it will update the cursor
-//          and reset the selection start/end to the cursor point. the x,y must
-//          be relative to the text widget, with (0,0) being the top left.
-//
-//      drag:
-//          call this with the mouse x,y on a mouse drag/up; it will update the
-//          cursor and the selection end point
-//
-//      cut:
-//          call this to delete the current selection; returns true if there was
-//          one. you should FIRST copy the current selection to the system paste buffer.
-//          (To copy, just copy the current selection out of the string yourself.)
-//
-//      paste:
-//          call this to paste text at the current cursor point or over the current
-//          selection if there is one.
-//
-//      key:
-//          call this for keyboard inputs sent to the textfield. you can use it
-//          for "key down" events or for "translated" key events. if you need to
-//          do both (as in Win32), or distinguish Unicode characters from control
-//          inputs, set a high bit to distinguish the two; then you can define the
-//          various definitions like STB_TEXTEDIT_K_LEFT have the is-key-event bit
-//          set, and make STB_TEXTEDIT_KEYTOCHAR check that the is-key-event bit is
-//          clear. STB_TEXTEDIT_KEYTYPE defaults to int, but you can #define it to
-//          anything other type you wante before including.
-//
-//
-//   When rendering, you can read the cursor position and selection state from
-//   the STB_TexteditState.
-//
-//
-// Notes:
-//
-// This is designed to be usable in IMGUI, so it allows for the possibility of
-// running in an IMGUI that has NOT cached the multi-line layout. For this
-// reason, it provides an interface that is compatible with computing the
-// layout incrementally--we try to make sure we make as few passes through
-// as possible. (For example, to locate the mouse pointer in the text, we
-// could define functions that return the X and Y positions of characters
-// and binary search Y and then X, but if we're doing dynamic layout this
-// will run the layout algorithm many times, so instead we manually search
-// forward in one pass. Similar logic applies to e.g. up-arrow and
-// down-arrow movement.)
-//
-// If it's run in a widget that *has* cached the layout, then this is less
-// efficient, but it's not horrible on modern computers. But you wouldn't
-// want to edit million-line files with it.

-// =======================================================================
-//
-//    NO SECURITY GUARANTEE -- DO NOT USE THIS ON UNTRUSTED FONT FILES
-//
-// This library does no range checking of the offsets found in the file,
-// meaning an attacker can use it to read arbitrary memory.
-//
-// =======================================================================
-//
-//   This library processes TrueType files:
-//        parse files
-//        extract glyph metrics
-//        extract glyph shapes
-//        render glyphs to one-channel bitmaps with antialiasing (box filter)
-//        render glyphs to one-channel SDF bitmaps (signed-distance field/function)
-//
-//   Todo:
-//        non-MS cmaps
-//        crashproof on bad data
-//        hinting? (no longer patented)
-//        cleartype-style AA?
-//        optimize: use simple memory allocator for intermediates
-//        optimize: build edge-list directly from curves
-//        optimize: rasterize directly from curves?

-// USAGE
-//
-//   Include this file in whatever places need to refer to it. In ONE C/C++
-//   file, write:
-//      #define STB_TRUETYPE_IMPLEMENTATION
-//   before the #include of this file. This expands out the actual
-//   implementation into that C/C++ file.
-//
-//   To make the implementation private to the file that generates the implementation,
-//      #define STBTT_STATIC
-//
-//   Simple 3D API (don't ship this, but it's fine for tools and quick start)
-//           stbtt_BakeFontBitmap()               -- bake a font to a bitmap for use as texture
-//           stbtt_GetBakedQuad()                 -- compute quad to draw for a given char
-//
-//   Improved 3D API (more shippable):
-//           #include "stb_rect_pack.h"           -- optional, but you really want it
-//           stbtt_PackBegin()
-//           stbtt_PackSetOversampling()          -- for improved quality on small fonts
-//           stbtt_PackFontRanges()               -- pack and renders
-//           stbtt_PackEnd()
-//           stbtt_GetPackedQuad()
-//
-//   "Load" a font file from a memory buffer (you have to keep the buffer loaded)
-//           stbtt_InitFont()
-//           stbtt_GetFontOffsetForIndex()        -- indexing for TTC font collections
-//           stbtt_GetNumberOfFonts()             -- number of fonts for TTC font collections
-//
-//   Render a unicode codepoint to a bitmap
-//           stbtt_GetCodepointBitmap()           -- allocates and returns a bitmap
-//           stbtt_MakeCodepointBitmap()          -- renders into bitmap you provide
-//           stbtt_GetCodepointBitmapBox()        -- how big the bitmap must be
-//
-//   Character advance/positioning
-//           stbtt_GetCodepointHMetrics()
-//           stbtt_GetFontVMetrics()
-//           stbtt_GetFontVMetricsOS2()
-//           stbtt_GetCodepointKernAdvance()
-//
-//   Starting with version 1.06, the rasterizer was replaced with a new,
-//   faster and generally-more-precise rasterizer. The new rasterizer more
-//   accurately measures pixel coverage for anti-aliasing, except in the case
-//   where multiple shapes overlap, in which case it overestimates the AA pixel
-//   coverage. Thus, anti-aliasing of intersecting shapes may look wrong. If
-//   this turns out to be a problem, you can re-enable the old rasterizer with
-//        #define STBTT_RASTERIZER_VERSION 1
-//   which will incur about a 15% speed hit.
-//
-// ADDITIONAL DOCUMENTATION
-//
-//   Immediately after this block comment are a series of sample programs.
-//
-//   After the sample programs is the "header file" section. This section
-//   includes documentation for each API function.
-//
-//   Some important concepts to understand to use this library:
-//
-//      Codepoint
-//         Characters are defined by unicode codepoints, e.g. 65 is
-//         uppercase A, 231 is lowercase c with a cedilla, 0x7e30 is
-//         the hiragana for "ma".
-//
-//      Glyph
-//         A visual character shape (every codepoint is rendered as
-//         some glyph)
-//
-//      Glyph index
-//         A font-specific integer ID representing a glyph
-//
-//      Baseline
-//         Glyph shapes are defined relative to a baseline, which is the
-//         bottom of uppercase characters. Characters extend both above
-//         and below the baseline.
-//
-//      Current Point
-//         As you draw text to the screen, you keep track of a "current point"
-//         which is the origin of each character. The current point's vertical
-//         position is the baseline. Even "baked fonts" use this model.
-//
-//      Vertical Font Metrics
-//         The vertical qualities of the font, used to vertically position
-//         and space the characters. See docs for stbtt_GetFontVMetrics.
-//
-//      Font Size in Pixels or Points
-//         The preferred interface for specifying font sizes in stb_truetype
-//         is to specify how tall the font's vertical extent should be in pixels.
-//         If that sounds good enough, skip the next paragraph.
-//
-//         Most font APIs instead use "points", which are a common typographic
-//         measurement for describing font size, defined as 72 points per inch.
-//         stb_truetype provides a point API for compatibility. However, true
-//         "per inch" conventions don't make much sense on computer displays
-//         since different monitors have different number of pixels per
-//         inch. For example, Windows traditionally uses a convention that
-//         there are 96 pixels per inch, thus making 'inch' measurements have
-//         nothing to do with inches, and thus effectively defining a point to
-//         be 1.333 pixels. Additionally, the TrueType font data provides
-//         an explicit scale factor to scale a given font's glyphs to points,
-//         but the author has observed that this scale factor is often wrong
-//         for non-commercial fonts, thus making fonts scaled in points
-//         according to the TrueType spec incoherently sized in practice.
-//
-// DETAILED USAGE:
-//
-//  Scale:
-//    Select how high you want the font to be, in points or pixels.
-//    Call ScaleForPixelHeight or ScaleForMappingEmToPixels to compute
-//    a scale factor SF that will be used by all other functions.
-//
-//  Baseline:
-//    You need to select a y-coordinate that is the baseline of where
-//    your text will appear. Call GetFontBoundingBox to get the baseline-relative
-//    bounding box for all characters. SF*-y0 will be the distance in pixels
-//    that the worst-case character could extend above the baseline, so if
-//    you want the top edge of characters to appear at the top of the
-//    screen where y=0, then you would set the baseline to SF*-y0.
-//
-//  Current point:
-//    Set the current point where the first character will appear. The
-//    first character could extend left of the current point; this is font
-//    dependent. You can either choose a current point that is the leftmost
-//    point and hope, or add some padding, or check the bounding box or
-//    left-side-bearing of the first character to be displayed and set
-//    the current point based on that.
-//
-//  Displaying a character:
-//    Compute the bounding box of the character. It will contain signed values
-//    relative to <current_point, baseline>. I.e. if it returns x0,y0,x1,y1,
-//    then the character should be displayed in the rectangle from
-//    <current_point+SF*x0, baseline+SF*y0> to <current_point+SF*x1,baseline+SF*y1).
-//
-//  Advancing for the next character:
-//    Call GlyphHMetrics, and compute 'current_point += SF * advance'.
-//
-//
-// ADVANCED USAGE
-//
-//   Quality:
-//
-//    - Use the functions with Subpixel at the end to allow your characters
-//      to have subpixel positioning. Since the font is anti-aliased, not
-//      hinted, this is very import for quality. (This is not possible with
-//      baked fonts.)
-//
-//    - Kerning is now supported, and if you're supporting subpixel rendering
-//      then kerning is worth using to give your text a polished look.
-//
-//   Performance:
-//
-//    - Convert Unicode codepoints to glyph indexes and operate on the glyphs;
-//      if you don't do this, stb_truetype is forced to do the conversion on
-//      every call.
-//
-//    - There are a lot of memory allocations. We should modify it to take
-//      a temp buffer and allocate from the temp buffer (without freeing),
-//      should help performance a lot.
-//
-// NOTES
-//
-//   The system uses the raw data found in the .ttf file without changing it
-//   and without building auxiliary data structures. This is a bit inefficient
-//   on little-endian systems (the data is big-endian), but assuming you're
-//   caching the bitmaps or glyph shapes this shouldn't be a big deal.
-//
-//   It appears to be very hard to programmatically determine what font a
-//   given file is in a general way. I provide an API for this, but I don't
-//   recommend it.
-//
-//
-// PERFORMANCE MEASUREMENTS FOR 1.06:
-//
-//                      32-bit     64-bit
-//   Previous release:  8.83 s     7.68 s
-//   Pool allocations:  7.72 s     6.34 s
-//   Inline sort     :  6.54 s     5.65 s
-//   New rasterizer  :  5.63 s     5.00 s

-//        glyph/codepoint   --  the character to generate the SDF for
-//        padding           --  extra "pixels" around the character which are filled with the distance to the character (not 0),
-//                                 which allows effects like bit outlines
-//        onedge_value      --  value 0-255 to test the SDF against to reconstruct the character (i.e. the isocontour of the character)
-//        pixel_dist_scale  --  what value the SDF should increase by when moving one SDF "pixel" away from the edge (on the 0..255 scale)
-//                                 if positive, > onedge_value is inside; if negative, < onedge_value is inside
-//        width,height      --  output height & width of the SDF bitmap (including padding)
-//        xoff,yoff         --  output origin of the character
-//        return value      --  a 2D array of bytes 0..255, width*height in size
-//
-// pixel_dist_scale & onedge_value are a scale & bias that allows you to make
-// optimal use of the limited 0..255 for your application, trading off precision
-// and special effects. SDF values outside the range 0..255 are clamped to 0..255.
-//
-// Example:
-//      scale = stbtt_ScaleForPixelHeight(22)
-//      padding = 5
-//      onedge_value = 180
-//      pixel_dist_scale = 180/5.0 = 36.0
-//
-//      This will create an SDF bitmap in which the character is about 22 pixels
-//      high but the whole bitmap is about 22+5+5=32 pixels high. To produce a filled
-//      shape, sample the SDF at each pixel and fill the pixel if the SDF value
-//      is greater than or equal to 180/255. (You'll actually want to antialias,
-//      which is beyond the scope of this example.) Additionally, you can compute
-//      offset outlines (e.g. to stroke the character border inside & outside,
-//      or only outside). For example, to fill outside the character up to 3 SDF
-//      pixels, you would compare against (180-36.0*3)/255 = 72/255. The above
-//      choice of variables maps a range from 5 pixels outside the shape to
-//      2 pixels inside the shape to 0..255; this is intended primarily for apply
-//      outside effects only (the interior range is needed to allow proper
-//      antialiasing of the font at *smaller* sizes)
-//
-// The function computes the SDF analytically at each SDF pixel, not by e.g.
-// building a higher-res bitmap and approximating it. In theory the quality
-// should be as high as possible for an SDF of this size & representation, but
-// unclear if this is true in practice (perhaps building a higher-res bitmap
-// and computing from that can allow drop-out prevention).
-//
-// The algorithm has not been optimized at all, so expect it to be slow
-// if computing lots of characters or very large sizes.

-// Finding the right font...
-//
-// You should really just solve this offline, keep your own tables
-// of what font is what, and don't try to get it out of the .ttf file.
-// That's because getting it out of the .ttf file is really hard, because
-// the names in the file can appear in many possible encodings, in many
-// possible languages, and e.g. if you need a case-insensitive comparison,
-// the details of that depend on the encoding & language in a complex way
-// (actually underspecified in truetype, but also gigantic).
-//
-// But you can use the provided functions in two possible ways:
-//     stbtt_FindMatchingFont() will use *case-sensitive* comparisons on
-//             unicode-encoded names to try to find the font you want;
-//             you can run this before calling stbtt_InitFont()
-//
-//     stbtt_GetFontNameString() lets you get any of the various strings
-//             from the file yourself and do your own comparisons on them.
-//             You have to have called stbtt_InitFont() first.
-
-
-STBTT_DEF int stbtt_FindMatchingFont(const unsigned char *fontdata, const char *name, int flags);
-// returns the offset (not index) of the font that matches, or -1 if none
-//   if you use STBTT_MACSTYLE_DONTCARE, use a font name like "Arial Bold".
-//   if you use any other flag, use a font name like "Arial"; this checks
-//     the 'macStyle' header field; i don't know if fonts set this consistently
