+// dear imgui: Platform Backend for QNX Screen
+// This needs to be used along with a Renderer Backend (e.g. OpenGL3, Vulkan).
+
+// Implemented features:
+//  [X] Platform: Keyboard support. Uses io.AddKeyEvent() and native QNX key symbols.
+//  [X] Platform: Mouse support. Handles position, three buttons and horizontal/vertical wheels.
+//  [X] Platform: Touch support. Maps the first active touch contact to the primary mouse button.
+//  [X] Platform: Focus and window-size updates.
+// Missing features or Issues:
+//  [ ] Platform: Clipboard support.
+//  [ ] Platform: Gamepad support.
+//  [ ] Platform: Mouse cursor shape and visibility (ImGuiBackendFlags_HasMouseCursors).
+//  [ ] Platform: Multi-viewport support.
+
+// CHANGELOG
+// (minor and older changes stripped away, please see git history for details)

+//  [X] Platform: Keyboard support. Uses io.AddKeyEvent() and native QNX key symbols.
+//  [X] Platform: Mouse support. Handles position, three buttons and horizontal/vertical wheels.
+//  [X] Platform: Touch support. Maps the first active touch contact to the primary mouse button.
+//  [X] Platform: Focus and window-size updates.
+// Missing features or Issues:
+//  [ ] Platform: Clipboard support.
+//  [ ] Platform: Gamepad support.
+//  [ ] Platform: Mouse cursor shape and visibility (ImGuiBackendFlags_HasMouseCursors).
+
+// 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.

 - Please report any issue!
 
+-----------------------------------------------------------------------
+ VERSION 1.93.0 WIP (In Progress)
+-----------------------------------------------------------------------
+
+Breaking Changes:
+
+- Style: obsoleted `style.CurveTessellationTol (default 1.25)` which was in Pixels² unit in
+  favor of `style.CurveTessellationMaxError` (default 1.12)` which is in Pixels unit. It is
+  easier to tweak + this allows us to easily scale error threshold on high density screens.
+  - style.CurveTessellationMaxError == sqrf(style.CurveTessellationTol).
+- ImGuiTextFilter: removed `float width` parameter of `Draw(const char* filter, float width)`:
+  prefer using `SetNextItemWidth(float)` which is standard. Kept inline redirection function.
+- Backends:
+  - DirectX12: Removed support for legacy `ImGui_ImplDX12_Init()` signature, which was
+    obsoleted in 1.91.6 (December 2014), because it needed to forcefully disable support
+    for `ImGuiBackendFlags_RendererHasTextures`. Use the new signature! (#9487)
+
+Other Changes:
+
+- Drags, Sliders:
+  - Fixed an overflow using `ImGuiSliderFlags_Logarithmic` with S32/S64 types which
+    leads to clamped interactions. (#9526, #3361, #1823, #1316, #642) [@lailoken]
+  - Ongoing drags may be cancelled using Right-Click, Escape or Gamepad Triangle.
+    Cancelling reverts to the initial value. (#8564, #9534)
+- TreeNode:
+  - Fixed issues/asserts with 32+ deep trees when using ImGuiTreeNodeFlags_DrawLinesXXX
+    features or other features requiring stack storage. (#9509) [@lasrod]
+- TabBar:
+  - Improved scroll target when clicking a Tab that is larger than the scrolling
+    section width.
+  - Using <> scrolling buttons while the selected Tab is at either end of the
+    section mid-section but not fully visible always makes it fully visible
+    (before eventually selecting a Tab in the leading/trailing section)
+- Tables:
+  - Fixed a bug restoring correct .ini columns order when table use is Sortable
+    but had no user changes. (regression from 1.92.9). (#9519, #9108)
+- InpuText:
+  - Fixed a crash in some cases when using Home key in a WordWrap+ReadOnly field. (#9561)
+- Selectable:
+  - Fixed `ImGuiSelectableFlags_SelectOnNav` triggering during NavInit.
+- Fonts:
+  - Reworked `AddFontDefault()` to use `io.DisplayFrameBufferScale` as part of the heuristic
+    to select `AddFontDefaultVector()` by default, effectively using ProggyForever instead of
+    ProggyClean on most Apple/Retina setups by default.
+  - imgui_freetype: Fixed blurryness rendering `AddFontDefaultVector()`. Caused by a
+    non-pixel aligned offset caused by `ExtraSizeScale`. (#9348, #9233) [@redpartizan, @RDMCz]
+- ColorEdit:
+  - ColorButton, ColorEdit, ColorPicker: cancel-out alpha caused by BeginDisabled() so
+    disabled color buttons have the same color as non-disabled oness. (#9511)
+  - ColorButton: fixed issues/inconsistencies with checkerboard rendering when combining
+    color alpha and global style alpha. (#9511) [@enjmiah, @ocornut]
+- Popups:
+  - Amended context menu right-click opening code to check that the right-click
+    hasn't been owned by another items. This is more correct and also necessary
+    to avoid Drags/Sliders cancelling also triggering a cancel menu. (#8564, #9534)
+  - Reworked `GetMousePosOnOpeningCurrentPopup()` to be legal to call within the
+    BeginPopup/EndPopup scope of a popup which was just closed. (#9551) [@jkunstwald]
+- ImGuiTextFilter:
+  - Added support for space as an "and" filter, which is the standard. (#2435, #30)
+     e.g. w/ filter 'hello world' (without quotes) both words needs to be in input data.
+  - Added support for double-quoted "xxx" blocks to e.g. match words sequences. (#2435)
+     e.g. w/ filter "hello world" the exact sequence needs to be in input data.
+  - Fixed filtering when mixing "include" and "-exclude" keyword so that an "-exclude"
+    match always filters out. (#2435) [@kudaba, @ocornut]
+  - Added `DrawWithHint()` function. (#6206, #6395, #6447)
+  - Added a "incl -excl" hint by default when the search field is empty. (#6206, #6395, #6447)
+- Style:
+  - Inverted `ImGuiCol_TitleBgXXX` colors for `StyleColorsLight()` so that the selected
+    window title bar appears brighter.
+- Misc:
+  - Added `ImGuiItemFlags_MixedValue` flag for representing mixed/indeterminate values.
+    Supported by: Checkbox(), RadioButton(), DragXXX(), SliderXXX(), InputXXX(), ColorXXX()
+    and Combo() functions.
+    The scoped flag is designed for usage by advanced property editors. (#5518, #5677, #6865)
+  - Fixed `GetBackgroundDrawList()`/`GetForegroundDrawList()` not being properly reset
+    every frame when cumulated session time is very large (e.g. a few days). [@lailoken]
+  - Added `IM_NODEBUGSTEP` helper to tag functions with `__declspec(non_user_code)` (MSVC)
+    or `[[gnu::artificial]]` (Clang/GCC) in order to provide a hint to debuggers to skip
+    trivial functions when stepping into.
+  - Tagged various trivial functions using `IM_NODEBUGSTEP`: `ImVec2()`, `ImVec4()` etc.
+    and various operators.
+  - Fixed strict aliasing violation in `ImHashData()` affecting Clang 23 + SSE 4.2 + -flto.
+    Could manifest as `ImFontAtlasBakedGetId()` computation omitting font size from
+    the hashed data. (#9557, #9560) [@sthalik]
+  - IO: restore default clipboard/ime/shell platform handlers on ClearPlatformHandlers(), fixing
+    issues switching backends mid-session to one relying on default. (#9537, #8945, #2769) [@lstalmir]
+- DrawList:
+  - Per-viewport FramebufferScale for Apple/Retina screen is applied to draw lists:
+    - AA Fringe is scaled accordingly.
+    - Circle and Curves tessellation error are scaled accordingly.
+  - Reworked assert in PushTexture() to allow convenience grace period of using a
+    texture that was queue for destroy during the frame. Make it safe to stick to
+    an existing texture during the frame. (#9528, #8465)
+  - Added optional `platform_io.DrawCallback_SetSamplerFromTex` standard backend-agnostic
+    draw callback for requesting to use the sampler associated already associated to a texture.
+    Currently only supported by the OpenGL2/3 and SDLRenderer3 backend. (#9378)
+  - Fixed dangling ImDrawList::_OwnerName when using animated label. (#9552) [@ubi-dcastonguay]
+- Demo:
+  - Added `Widgets->Mixed Values` section. (#5518, #5677, #6865)
+  - Style Editor: fixed style/colors combo box applying style when opening Combo.
+- Backends:
+  - QNX: added QNX Screen backend. (#9492) [@mgorchak-blackberry]
+  - OpenGL2, OpenGL3: added support for `platform_io.DrawCallback_SetSamplerFromTex` draw
+    callback to request using the sampler associated already associated to a texture. (#9378)
+  - OpenGL2, OpenGL3: fixed `DrawCallback_ResetRenderState` handler not reseting all states
+    in the glTexParameter() path. (#9378)
+  - SDL2: fixed querying framebuffer scale/density when using Metal without
+    going through a SDL_Renderer. (#5592) [@lailoken]
+  - SDLRenderer3: restore any temporarily modified texture scale modes at the of `RenderDrawData()`. (#9378)
+  - SDLRenderer3: expose CurrentScaleMode in ImGui_ImplSDLRenderer3_RenderState. (#9543, #9378) [@Clownacy]
+  - SDLRenderer3: added support for `platform_io.DrawCallback_SetSamplerFromTex` draw callback to request
+    using the sampler associated already associated to a texture via `SDL_SetTextureScaleMode()`. (#9378)
+    It is equivalent to setting `render_state->CurrentScaleMode = SDL_SCALEMODE_INVALID`.
+    Note: this  callback is only supported by selected rendering backends: most other graphics API
+    don't have the equivalent of `SDL_SetTextureScaleMode()` and the callback won't work with them.
+  - Vulkan: added for support for multiple Vulkan contexts with custom loaders. (#6616) [@lstalmir]
+  - WebGPU: fixed passing non-integer sizes to `wgpuRenderPassEncoderSetViewport()`
+    when `FramebufferScale` is >1.0f. (#9515, #8628) [@WayU]
+  - WebGPU: update to build with wgpu-native 29.0+. (#9377, #9532, #9530) [@lucascompython, @ivan-enzhaev]
+- Examples:
+  - MSVC: disabled /JMC in Visual Studio projects (unnecessary overhead).
+  - GLFW/SDL2/SDL3+WebGPU: fixed running with wgpu-native missing `wgpuInstanceWaitAny()`. (#9377)
+  - SDL2+Metal: create Metal context without using a `SDL_Renderer`.
+  - QNX+OpenGL3, QNX+Vulkan: added QNX Screen examples. (#9492) [@mgorchak-blackberry]
+  - OSX+OpenGL3: added example_apple_opengl3/ (OSX/Cocoa + OpenGL 3.2 Core profile).

    We intentionally do not provide an `ImTextureRef` constructor for this: we don't expect this to be frequently useful to the end-user, and it would be erroneously called by many legacy code.
  - There is no constructor to create a `ImTextureRef` from a `ImTextureData*` as we don't expect this to be useful to the end-user, and it would be erroneously called by many legacy code.
  - If you want to bind the current atlas when using custom rectangles, you can use `io.Fonts->TexRef`.

 v1.92 introduces a newer, dynamic font system. It requires backend to support the `ImGuiBackendFlags_HasTextures` feature:
 - Users of icons, Asian and non-English languages do not need to pre-build all glyphs ahead of time. Saving on loading time, memory, and also reducing issues with missing glyphs. Specifying glyph ranges is not needed anymore.
-- `PushFont(NULL, new_size)` may be used anytime to change font size.
+- `PushFont(nullptr, new_size)` may be used anytime to change font size.
 - Packing custom rectangles is more convenient as pixels may be written to immediately.
 - Any update to fonts previously required backend specific calls to re-upload the texture, and said calls were not portable across backends. It is now possible to scale fonts etc. in a way that doesn't require you to make backend-specific calls.
 - It is possible to plug a custom loader/backend to any font source.

+# Dear ImGui QNX Screen + OpenGL ES 3 example
+
+This example uses:
+
+- `imgui_impl_qnx.cpp` as the QNX Screen platform backend
+- `imgui_impl_opengl3.cpp` as the renderer backend
+- EGL to create an OpenGL ES 3 context and Screen window surface
+
+`imgui_impl_opengl3.cpp` supports desktop OpenGL and OpenGL ES. On QNX this
+example compiles it with `IMGUI_IMPL_OPENGL_ES3` and uses `#version 300 es`.
+No separate Screen/OpenGL renderer backend is required.
+
+## Build
+
+Load the QNX SDP environment, then run:
+
+```sh
+cd examples/example_qnx_opengl3
+make
+```
+
+The QNX recursive make files build for the CPUs enabled in your SDP
+configuration and install the program as `example_qnx_opengl3`.
+
+## Input
+
+The application polls its `screen_context_t` event queue and forwards every
+non-`SCREEN_EVENT_NONE` event to `ImGui_ImplQNX_ProcessEvent()`.
+Escape exits the example.

+# Dear ImGui QNX Screen + Vulkan example
+
+This example uses:
+
+- `imgui_impl_qnx.cpp` as the QNX Screen platform backend
+- the unmodified `imgui_impl_vulkan.cpp` renderer backend
+- `vkCreateScreenSurfaceQNX()` and `VK_QNX_screen_surface`
+
+No separate Screen/Vulkan renderer backend is required. The QNX-specific work
+is limited to the Screen platform backend, native window setup, and Vulkan WSI
+surface creation.
+
+## Build
+
+Load the QNX SDP environment, then run:
+
+```sh
+cd examples/example_qnx_vulkan
+make
+```
+
+The build defines `VK_USE_PLATFORM_SCREEN_QNX` and links `libvulkan` and
+`libscreen`.
+
+## Input and resize
+
+The application forwards Screen input events to `ImGui_ImplQNX_ProcessEvent()`.
+It recreates the Vulkan swapchain when the Screen window size changes or Vulkan
+reports `VK_ERROR_OUT_OF_DATE_KHR` / `VK_SUBOPTIMAL_KHR`. Escape exits.

+// Dear ImGui: standalone example application for QNX Screen + Vulkan
+
+// 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
+
+// Important note to the reader who wish to integrate imgui_impl_vulkan.cpp/.h in their own engine/app.
+// - Common ImGui_ImplVulkan_XXX functions and structures are used to interface with imgui_impl_vulkan.cpp/.h.
+//   You will use those if you want to use this rendering backend in your engine/app.
+// - Helper ImGui_ImplVulkanH_XXX functions and structures are only used by this example (main.cpp) and by
+//   the backend itself (imgui_impl_vulkan.cpp), but should PROBABLY NOT be used by your own engine/app code.
+// Read comments in imgui_impl_vulkan.h.
