+ FOR FIRST-TIME USERS ISSUES COMPILING/LINKING/RUNNING, please use [GitHub Discussions](https://github.com/ocornut/imgui/discussions)
+ For anything else: **we are happy to use 'GitHub Issues' for many types of open-ended questions**. We are encouraging 'Issues' becoming a large, centralized, tagged, cross-referenced database of Dear ImGui contents.
+
+ Be mindful that messages are being sent to the e-mail box of "Watching" users. Try to proof-read your messages before sending them. Edits are not seen by those users.
+
+ **If you are using Dear ImGui as part of a job that you are being well-paid for** and your company is not a sponsor. Please be mindful that this is a Free Software and you might be about to ask volunteers to help you doing your job. Please put extra effort describing your issue or question properly. If your company is wealthy, please read [Funding](https://github.com/ocornut/imgui/wiki/Funding) and consider getting in touch.

An ideal submission includes a small piece of code that anyone can paste into one of the examples applications (examples/*/main.cpp) or the demo (imgui_demo.cpp) to understand and reproduce it. Narrowing your problem to its shortest and purest form is the easiest way to understand it, explain it and fix it. Please test your shortened code to ensure it exhibits the problem. Often while creating the MCVE you will solve the problem! Many questions that are missing a standalone verifiable example are missing the actual cause of their issue in the description, which ends up wasting everyone's time."

+// dear imgui: Renderer + Platform Backend for Allegro 5
+// (Info: Allegro 5 is a cross-platform general purpose library for handling windows, inputs, graphics, etc.)
+
+// Implemented features:
+// [X] Renderer: User texture binding. Use 'ALLEGRO_BITMAP*' as texture identifier. Read the FAQ about ImTextureID/ImTextureRef!
+// [X] Renderer: Texture updates support for dynamic font atlas (ImGuiBackendFlags_RendererHasTextures).
+// [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 ALLEGRO_KEY_* values are obsolete since 1.87 and not supported since 1.91.5]
+// [X] Platform: Clipboard support (from Allegro 5.1.12).
+// [X] Platform: Mouse cursor shape and visibility (ImGuiBackendFlags_HasMouseCursors). Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'.
+// Missing features or Issues:
+// [ ] Renderer: The renderer is suboptimal as we need to unindex our buffers and convert vertices manually.
+// [ ] Platform: Missing gamepad support.
+
+// 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
+
+// CHANGELOG
+// (minor and older changes stripped away, please see git history for details)
+// 2025-09-18: Call platform_io.ClearRendererHandlers() and platform_io.ClearPlatformHandlers() on shutdown.
+// 2025-08-12: Inputs: fixed missing support for ImGuiKey_PrintScreen under Windows, as raw Allegro 5 does not receive it.
+// 2025-08-12: Added ImGui_ImplAllegro5_SetDisplay() function to change current ALLEGRO_DISPLAY, as Allegro applications often need to do that.
+// 2025-07-07: Fixed texture update broken on some platforms where ALLEGRO_LOCK_WRITEONLY needed all texels to be rewritten.
+// 2025-06-11: Added support for ImGuiBackendFlags_RendererHasTextures, for dynamic font atlas. Removed ImGui_ImplSDLGPU3_CreateFontsTexture() and ImGui_ImplSDLGPU3_DestroyFontsTexture().
+// 2025-02-18: Added ImGuiMouseCursor_Wait and ImGuiMouseCursor_Progress mouse cursor support.
+// 2025-01-06: Avoid calling al_set_mouse_cursor() repeatedly since it appears to leak on on X11 (#8256).
+// 2024-08-22: moved some OS/backend related function pointers from ImGuiIO to ImGuiPlatformIO:
+// - io.GetClipboardTextFn -> platform_io.Platform_GetClipboardTextFn
+// - io.SetClipboardTextFn -> platform_io.Platform_SetClipboardTextFn
+// 2022-11-30: Renderer: Restoring using al_draw_indexed_prim() when Allegro version is >= 5.2.5.
+// 2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
+// 2022-09-26: Inputs: Renamed ImGuiKey_ModXXX introduced in 1.87 to ImGuiMod_XXX (old names still supported).
+// 2022-01-26: Inputs: replaced short-lived io.AddKeyModsEvent() (added two weeks ago) with io.AddKeyEvent() using ImGuiKey_ModXXX flags. Sorry for the confusion.
+// 2022-01-17: Inputs: calling new io.AddMousePosEvent(), io.AddMouseButtonEvent(), io.AddMouseWheelEvent() API (1.87+).
+// 2022-01-17: Inputs: always calling io.AddKeyModsEvent() next and before key event (not in NewFrame) to fix input queue with very low framerates.
+// 2022-01-10: Inputs: calling new io.AddKeyEvent(), io.AddKeyModsEvent() + io.SetKeyEventNativeData() API (1.87+). Support for full ImGuiKey range.
+// 2021-12-08: Renderer: 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.
+// 2021-08-17: Calling io.AddFocusEvent() on ALLEGRO_EVENT_DISPLAY_SWITCH_OUT/ALLEGRO_EVENT_DISPLAY_SWITCH_IN events.
+// 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: Renderer: Replaced direct access to ImDrawCmd::TextureId with a call to ImDrawCmd::GetTexID(). (will become a requirement)
+// 2021-02-18: Change blending equation to preserve alpha in output buffer.
+// 2020-08-10: Inputs: Fixed horizontal mouse wheel direction.
+// 2019-12-05: Inputs: Added support for ImGuiMouseCursor_NotAllowed mouse cursor.
+// 2019-07-21: Inputs: Added mapping for ImGuiKey_KeyPadEnter.
+// 2019-05-11: Inputs: Don't filter character value from ALLEGRO_EVENT_KEY_CHAR before calling AddInputCharacter().
+// 2019-04-30: Renderer: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
+// 2018-11-30: Platform: Added touchscreen support.
+// 2018-11-30: Misc: Setting up io.BackendPlatformName/io.BackendRendererName so they can be displayed in the About Window.
+// 2018-06-13: Platform: Added clipboard support (from Allegro 5.1.12).
+// 2018-06-13: Renderer: Use draw_data->DisplayPos and draw_data->DisplaySize to setup projection matrix and clipping rectangle.
+// 2018-06-13: Renderer: Stopped using al_draw_indexed_prim() as it is buggy in Allegro's DX9 backend.
+// 2018-06-13: Renderer: Backup/restore transform and clipping rectangle.
+// 2018-06-11: Misc: Setup io.BackendFlags ImGuiBackendFlags_HasMouseCursors flag + honor ImGuiConfigFlags_NoMouseCursorChange flag.
+// 2018-04-18: Misc: Renamed file from imgui_impl_a5.cpp to imgui_impl_allegro5.cpp.
+// 2018-04-18: Misc: Added support for 32-bit vertex indices to avoid conversion at runtime. Added imconfig_allegro5.h to enforce 32-bit indices when included from imgui.h.
+// 2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback and exposed ImGui_ImplAllegro5_RenderDrawData() in the .h file so you can call it yourself.
+// 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.

+// [X] Platform: Mouse cursor shape and visibility (ImGuiBackendFlags_HasMouseCursors). Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'.
+// Missing features or Issues:
+// [ ] Renderer: The renderer is suboptimal as we need to unindex our buffers and convert vertices manually.
+// [ ] Platform: Missing gamepad support.

+// [X] Platform: Mouse support. Can discriminate Mouse/TouchScreen/Pen.
+// Missing features or Issues:
+// [ ] Platform: Clipboard support.
+// [ ] Platform: Gamepad support.
+// [ ] Platform: Mouse cursor shape and visibility (ImGuiBackendFlags_HasMouseCursors). Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'. FIXME: Check if this is even possible with Android.
+// Important:
+// - Consider using SDL or GLFW backend on Android, which will be more full-featured than this.
+// - FIXME: On-screen keyboard currently needs to be enabled by the application (see examples/ and issue #3446)
+// - FIXME: Unicode character inputs needs to be passed by Dear ImGui by the application (see examples/ and issue #3446)
+
+// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.

+// CHANGELOG
+// (minor and older changes stripped away, please see git history for details)
+// 2025-09-18: Call platform_io.ClearRendererHandlers() on shutdown.
+// 2025-06-11: DirectX10: Added support for ImGuiBackendFlags_RendererHasTextures, for dynamic font atlas.
+// 2025-05-07: DirectX10: Honor draw_data->FramebufferScale to allow for custom backends and experiment using it (consistently with other renderer backends, even though in normal condition it is not set under Windows).
+// 2025-01-06: DirectX10: Expose selected render state in ImGui_ImplDX10_RenderState, which you can access in 'void* platform_io.Renderer_RenderState' during draw callbacks.
+// 2024-10-07: DirectX10: Changed default texture sampler to Clamp instead of Repeat/Wrap.
+// 2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
+// 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: DirectX10: Replaced direct access to ImDrawCmd::TextureId with a call to ImDrawCmd::GetTexID(). (will become a requirement)
+// 2021-02-18: DirectX10: Change blending equation to preserve alpha in output buffer.
+// 2019-07-21: DirectX10: Backup, clear and restore Geometry Shader is any is bound when calling ImGui_ImplDX10_RenderDrawData().
+// 2019-05-29: DirectX10: Added support for large mesh (64K+ vertices), enable ImGuiBackendFlags_RendererHasVtxOffset flag.
+// 2019-04-30: DirectX10: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
+// 2018-12-03: Misc: Added #pragma comment statement to automatically link with d3dcompiler.lib when using D3DCompile().
+// 2018-11-30: Misc: Setting up io.BackendRendererName so it can be displayed in the About Window.
+// 2018-07-13: DirectX10: Fixed unreleased resources in Init and Shutdown functions.
+// 2018-06-08: Misc: Extracted imgui_impl_dx10.cpp/.h away from the old combined DX10+Win32 example.
+// 2018-06-08: DirectX10: Use draw_data->DisplayPos and draw_data->DisplaySize to setup projection matrix and clipping rectangle.
+// 2018-04-09: Misc: Fixed erroneous call to io.Fonts->ClearInputData() + ClearTexData() that was left in DX10 example but removed in 1.47 (Nov 2015) on other backends.
+// 2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback and exposed ImGui_ImplDX10_RenderDrawData() in the .h file so you can call it yourself.
+// 2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.
+// 2016-05-07: DirectX10: Disabling depth-write.

+// (minor and older changes stripped away, please see git history for details)
+// 2025-09-18: Call platform_io.ClearRendererHandlers() on shutdown.
+// 2025-06-11: DirectX11: Added support for ImGuiBackendFlags_RendererHasTextures, for dynamic font atlas.
+// 2025-05-07: DirectX11: Honor draw_data->FramebufferScale to allow for custom backends and experiment using it (consistently with other renderer backends, even though in normal condition it is not set under Windows).
+// 2025-01-06: DirectX11: Expose VertexConstantBuffer in ImGui_ImplDX11_RenderState. Reset projection matrix in ImDrawCallback_ResetRenderState handler.
+// 2024-10-07: DirectX11: Changed default texture sampler to Clamp instead of Repeat/Wrap.
+// 2024-10-07: DirectX11: Expose selected render state in ImGui_ImplDX11_RenderState, which you can access in 'void* platform_io.Renderer_RenderState' during draw callbacks.
+// 2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
+// 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: DirectX11: Replaced direct access to ImDrawCmd::TextureId with a call to ImDrawCmd::GetTexID(). (will become a requirement)
+// 2021-02-18: DirectX11: Change blending equation to preserve alpha in output buffer.
+// 2019-08-01: DirectX11: Fixed code querying the Geometry Shader state (would generally error with Debug layer enabled).
+// 2019-07-21: DirectX11: Backup, clear and restore Geometry Shader is any is bound when calling ImGui_ImplDX11_RenderDrawData. Clearing Hull/Domain/Compute shaders without backup/restore.
+// 2019-05-29: DirectX11: Added support for large mesh (64K+ vertices), enable ImGuiBackendFlags_RendererHasVtxOffset flag.
+// 2019-04-30: DirectX11: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
+// 2018-12-03: Misc: Added #pragma comment statement to automatically link with d3dcompiler.lib when using D3DCompile().
+// 2018-11-30: Misc: Setting up io.BackendRendererName so it can be displayed in the About Window.
+// 2018-08-01: DirectX11: Querying for IDXGIFactory instead of IDXGIFactory1 to increase compatibility.
+// 2018-07-13: DirectX11: Fixed unreleased resources in Init and Shutdown functions.
+// 2018-06-08: Misc: Extracted imgui_impl_dx11.cpp/.h away from the old combined DX11+Win32 example.
+// 2018-06-08: DirectX11: 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_ImplDX11_RenderDrawData() in the .h file so you can call it yourself.
+// 2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.
+// 2016-05-07: DirectX11: Disabling depth-write.

+// CHANGELOG
+// (minor and older changes stripped away, please see git history for details)
+// 2025-10-11: DirectX12: Reuse texture upload buffer and grow it only when necessary. (#9002)
+// 2025-09-29: DirectX12: Rework synchronization logic. (#8961)
+// 2025-09-29: DirectX12: Enable swapchain tearing to eliminate viewports framerate throttling. (#8965)
+// 2025-09-29: DirectX12: Reuse a command list and allocator for texture uploads instead of recreating them each time. (#8963)
+// 2025-09-18: Call platform_io.ClearRendererHandlers() on shutdown.
+// 2025-06-19: Fixed build on MinGW. (#8702, #4594)
+// 2025-06-11: DirectX12: Added support for ImGuiBackendFlags_RendererHasTextures, for dynamic font atlas.
+// 2025-05-07: DirectX12: Honor draw_data->FramebufferScale to allow for custom backends and experiment using it (consistently with other renderer backends, even though in normal condition it is not set under Windows).
+// 2025-02-24: DirectX12: Fixed an issue where ImGui_ImplDX12_Init() signature change from 2024-11-15 combined with change from 2025-01-15 made legacy ImGui_ImplDX12_Init() crash. (#8429)
+// 2025-01-15: DirectX12: Texture upload use the command queue provided in ImGui_ImplDX12_InitInfo instead of creating its own.
+// 2024-12-09: DirectX12: Let user specifies the DepthStencilView format by setting ImGui_ImplDX12_InitInfo::DSVFormat.
+// 2024-11-15: DirectX12: *BREAKING CHANGE* Changed ImGui_ImplDX12_Init() signature to take a ImGui_ImplDX12_InitInfo struct. Legacy ImGui_ImplDX12_Init() signature is still supported (will obsolete).
+// 2024-11-15: DirectX12: *BREAKING CHANGE* User is now required to pass function pointers to allocate/free SRV Descriptors. We provide convenience legacy fields to pass a single descriptor, matching the old API, but upcoming features will want multiple.
+// 2024-10-23: DirectX12: Unmap() call specify written range. The range is informational and may be used by debug tools.
+// 2024-10-07: DirectX12: Changed default texture sampler to Clamp instead of Repeat/Wrap.
+// 2024-10-07: DirectX12: Expose selected render state in ImGui_ImplDX12_RenderState, which you can access in 'void* platform_io.Renderer_RenderState' during draw callbacks.
+// 2024-10-07: DirectX12: Compiling with '#define ImTextureID=ImU64' is unnecessary now that dear imgui defaults ImTextureID to u64 instead of void*.
+// 2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
+// 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: DirectX12: Replaced direct access to ImDrawCmd::TextureId with a call to ImDrawCmd::GetTexID(). (will become a requirement)
+// 2021-02-18: DirectX12: Change blending equation to preserve alpha in output buffer.
+// 2021-01-11: DirectX12: Improve Windows 7 compatibility (for D3D12On7) by loading d3d12.dll dynamically.
+// 2020-09-16: DirectX12: Avoid rendering calls with zero-sized scissor rectangle since it generates a validation layer warning.
+// 2020-09-08: DirectX12: Clarified support for building on 32-bit systems by redefining ImTextureID.
+// 2019-10-18: DirectX12: *BREAKING CHANGE* Added extra ID3D12DescriptorHeap parameter to ImGui_ImplDX12_Init() function.
+// 2019-05-29: DirectX12: Added support for large mesh (64K+ vertices), enable ImGuiBackendFlags_RendererHasVtxOffset flag.
+// 2019-04-30: DirectX12: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
+// 2019-03-29: Misc: Various minor tidying up.
+// 2018-12-03: Misc: Added #pragma comment statement to automatically link with d3dcompiler.lib when using D3DCompile().
+// 2018-11-30: Misc: Setting up io.BackendRendererName so it can be displayed in the About Window.
+// 2018-06-12: DirectX12: Moved the ID3D12GraphicsCommandList* parameter from NewFrame() to RenderDrawData().
+// 2018-06-08: Misc: Extracted imgui_impl_dx12.cpp/.h away from the old combined DX12+Win32 example.
+// 2018-06-08: DirectX12: Use draw_data->DisplayPos and draw_data->DisplaySize to setup projection matrix and clipping rectangle (to ease support for future multi-viewport).
+// 2018-02-22: Merged into master with all Win32 code synchronized to other examples.

+// CHANGELOG
+// (minor and older changes stripped away, please see git history for details)
+// 2025-09-18: Call platform_io.ClearRendererHandlers() on shutdown.
+// 2025-06-11: DirectX9: Added support for ImGuiBackendFlags_RendererHasTextures, for dynamic font atlas.
+// 2024-10-07: DirectX9: Changed default texture sampler to Clamp instead of Repeat/Wrap.
+// 2024-02-12: DirectX9: Using RGBA format when supported by the driver to avoid CPU side conversion. (#6575)
+// 2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
+// 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).
+// 2021-06-25: DirectX9: Explicitly disable texture state stages after >= 1.
+// 2021-05-19: DirectX9: Replaced direct access to ImDrawCmd::TextureId with a call to ImDrawCmd::GetTexID(). (will become a requirement)
+// 2021-04-23: DirectX9: Explicitly setting up more graphics states to increase compatibility with unusual non-default states.
+// 2021-03-18: DirectX9: Calling IDirect3DStateBlock9::Capture() after CreateStateBlock() as a workaround for state restoring issues (see #3857).
+// 2021-03-03: DirectX9: Added support for IMGUI_USE_BGRA_PACKED_COLOR in user's imconfig file.
+// 2021-02-18: DirectX9: Change blending equation to preserve alpha in output buffer.
+// 2019-05-29: DirectX9: Added support for large mesh (64K+ vertices), enable ImGuiBackendFlags_RendererHasVtxOffset flag.
+// 2019-04-30: DirectX9: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
+// 2019-03-29: Misc: Fixed erroneous assert in ImGui_ImplDX9_InvalidateDeviceObjects().
+// 2019-01-16: Misc: Disabled fog before drawing UI's. Fixes issue #2288.
+// 2018-11-30: Misc: Setting up io.BackendRendererName so it can be displayed in the About Window.
+// 2018-06-08: Misc: Extracted imgui_impl_dx9.cpp/.h away from the old combined DX9+Win32 example.
+// 2018-06-08: DirectX9: Use draw_data->DisplayPos and draw_data->DisplaySize to setup projection matrix and clipping rectangle.
+// 2018-05-07: Render: Saving/restoring Transform because they don't seem to be included in the StateBlock. Setting shading mode to Gouraud.
+// 2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback and exposed ImGui_ImplDX9_RenderDrawData() in the .h file so you can call it yourself.
+// 2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.

+// dear imgui: Platform Backend for GLFW
+// This needs to be used along with a Renderer (e.g. OpenGL3, Vulkan, WebGPU..)
+// (Info: GLFW is a cross-platform general purpose library for handling windows, inputs, OpenGL/Vulkan graphics context creation, etc.)
+// (Requires: GLFW 3.0+. Prefer GLFW 3.3+/3.4+ for full feature support.)
+
+// Implemented features:
+// [X] Platform: Clipboard support.
+// [X] Platform: Mouse support. Can discriminate Mouse/TouchScreen/Pen (Windows only).
+// [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 GLFW_KEY_* values are obsolete since 1.87 and not supported since 1.91.5]
+// [X] Platform: Gamepad support. Enable with 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad'.
+// [X] Platform: Mouse cursor shape and visibility (ImGuiBackendFlags_HasMouseCursors) with GLFW 3.1+. Resizing cursors requires GLFW 3.4+! Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'.
+// [X] Multiple Dear ImGui contexts support.
+// Missing features or Issues:
+// [ ] Touch events are only correctly identified as Touch on Windows. This create issues with some interactions. GLFW doesn't provide a way to identify touch inputs from mouse inputs, we cannot call io.AddMouseSourceEvent() to identify the source. We provide a Windows-specific workaround.
+// [ ] Missing ImGuiMouseCursor_Wait and ImGuiMouseCursor_Progress cursors.
+
+// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.

+// - Documentation https://dearimgui.com/docs (same as your local docs/ folder).
+// - Introduction, links and more at the top of imgui.cpp
+
+// About Emscripten support:
+// - Emscripten provides its own GLFW (3.2.1) implementation (syntax: "-sUSE_GLFW=3"), but Joystick is broken and several features are not supported (multiple windows, clipboard, timer, etc.)
+// - A third-party Emscripten GLFW (3.4.0) implementation (syntax: "--use-port=contrib.glfw3") fixes the Joystick issue and implements all relevant features for the browser.
+// See https://github.com/pongasoft/emscripten-glfw/blob/master/docs/Comparison.md for details.
+
+// CHANGELOG
+// (minor and older changes stripped away, please see git history for details)
+// 2025-11-06: Lower minimum requirement to GLFW 3.0. Though a recent version e.g GLFW 3.4 is highly recommended.
+// 2025-09-18: Call platform_io.ClearPlatformHandlers() on shutdown.
+// 2025-09-15: Content Scales are always reported as 1.0 on Wayland. FramebufferScale are always reported as 1.0 on X11. (#8920, #8921)
+// 2025-07-08: Made ImGui_ImplGlfw_GetContentScaleForWindow(), ImGui_ImplGlfw_GetContentScaleForMonitor() helpers return 1.0f on Emscripten and Android platforms, matching macOS logic. (#8742, #8733)
+// 2025-06-18: Added support for multiple Dear ImGui contexts. (#8676, #8239, #8069)
+// 2025-06-11: Added ImGui_ImplGlfw_GetContentScaleForWindow(GLFWwindow* window) and ImGui_ImplGlfw_GetContentScaleForMonitor(GLFWmonitor* monitor) helper to facilitate making DPI-aware apps.
+// 2025-03-10: Map GLFW_KEY_WORLD_1 and GLFW_KEY_WORLD_2 into ImGuiKey_Oem102.
+// 2025-03-03: Fixed clipboard handler assertion when using GLFW <= 3.2.1 compiled with asserts enabled.
+// 2024-08-22: Moved some OS/backend related function pointers from ImGuiIO to ImGuiPlatformIO:
+// - io.GetClipboardTextFn -> platform_io.Platform_GetClipboardTextFn
+// - io.SetClipboardTextFn -> platform_io.Platform_SetClipboardTextFn
+// - io.PlatformOpenInShellFn -> platform_io.Platform_OpenInShellFn
+// 2024-07-31: Added ImGui_ImplGlfw_Sleep() helper function for usage by our examples app, since GLFW doesn't provide one.
+// 2024-07-08: *BREAKING* Renamed ImGui_ImplGlfw_InstallEmscriptenCanvasResizeCallback to ImGui_ImplGlfw_InstallEmscriptenCallbacks(), added GLFWWindow* parameter.
+// 2024-07-08: Emscripten: Added support for GLFW3 contrib port (GLFW 3.4.0 features + bug fixes): to enable, replace -sUSE_GLFW=3 with --use-port=contrib.glfw3 (requires emscripten 3.1.59+) (https://github.com/pongasoft/emscripten-glfw)
+// 2024-07-02: Emscripten: Added io.PlatformOpenInShellFn() handler for Emscripten versions.
+// 2023-12-19: Emscripten: Added ImGui_ImplGlfw_InstallEmscriptenCanvasResizeCallback() to register canvas selector and auto-resize GLFW window.
+// 2023-10-05: Inputs: Added support for extra ImGuiKey values: F13 to F24 function keys.
+// 2023-07-18: Inputs: Revert ignoring mouse data on GLFW_CURSOR_DISABLED as it can be used differently. User may set ImGuiConfigFLags_NoMouse if desired. (#5625, #6609)
+// 2023-06-12: Accept glfwGetTime() not returning a monotonically increasing value. This seems to happens on some Windows setup when peripherals disconnect, and is likely to also happen on browser + Emscripten. (#6491)
+// 2023-04-04: Inputs: Added support for io.AddMouseSourceEvent() to discriminate ImGuiMouseSource_Mouse/ImGuiMouseSource_TouchScreen/ImGuiMouseSource_Pen on Windows ONLY, using a custom WndProc hook. (#2702)
+// 2023-03-16: Inputs: Fixed key modifiers handling on secondary viewports (docking branch). Broken on 2023/01/04. (#6248, #6034)
+// 2023-03-14: Emscripten: Avoid using glfwGetError() and glfwGetGamepadState() which are not correctly implemented in Emscripten emulation. (#6240)
+// 2023-02-03: Emscripten: Registering custom low-level mouse wheel handler to get more accurate scrolling impulses on Emscripten. (#4019, #6096)
+// 2023-01-04: Inputs: Fixed mods state on Linux when using Alt-GR text input (e.g. German keyboard layout), could lead to broken text input. Revert a 2022/01/17 change were we resumed using mods provided by GLFW, turns out they were faulty.
+// 2022-11-22: Perform a dummy glfwGetError() read to cancel missing names with glfwGetKeyName(). (#5908)
+// 2022-10-18: Perform a dummy glfwGetError() read to cancel missing mouse cursors errors. Using GLFW_VERSION_COMBINED directly. (#5785)
+// 2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
+// 2022-09-26: Inputs: Renamed ImGuiKey_ModXXX introduced in 1.87 to ImGuiMod_XXX (old names still supported).
+// 2022-09-01: Inputs: Honor GLFW_CURSOR_DISABLED by not setting mouse position *EDIT* Reverted 2023-07-18.
+// 2022-04-30: Inputs: Fixed ImGui_ImplGlfw_TranslateUntranslatedKey() for lower case letters on OSX.
+// 2022-03-23: Inputs: Fixed a regression in 1.87 which resulted in keyboard modifiers events being reported incorrectly on Linux/X11.
+// 2022-02-07: Added ImGui_ImplGlfw_InstallCallbacks()/ImGui_ImplGlfw_RestoreCallbacks() helpers to facilitate user installing callbacks after initializing backend.
+// 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: *BREAKING CHANGE*: Now using glfwSetCursorPosCallback(). If you called ImGui_ImplGlfw_InitXXX() with install_callbacks = false, you MUST install glfwSetCursorPosCallback() and forward it to the backend via ImGui_ImplGlfw_CursorPosCallback().
+// 2022-01-10: Inputs: calling new io.AddKeyEvent(), io.AddKeyModsEvent() + io.SetKeyEventNativeData() API (1.87+). Support for full ImGuiKey range.
+// 2022-01-05: Inputs: Converting GLFW untranslated keycodes back to translated keycodes (in the ImGui_ImplGlfw_KeyCallback() function) in order to match the behavior of every other backend, and facilitate the use of GLFW with lettered-shortcuts API.
+// 2021-08-17: *BREAKING CHANGE*: Now using glfwSetWindowFocusCallback() to calling io.AddFocusEvent(). If you called ImGui_ImplGlfw_InitXXX() with install_callbacks = false, you MUST install glfwSetWindowFocusCallback() and forward it to the backend via ImGui_ImplGlfw_WindowFocusCallback().
+// 2021-07-29: *BREAKING CHANGE*: Now using glfwSetCursorEnterCallback(). MousePos is correctly reported when the host platform window is hovered but not focused. If you called ImGui_ImplGlfw_InitXXX() with install_callbacks = false, you MUST install glfwSetWindowFocusCallback() callback and forward it to the backend via ImGui_ImplGlfw_CursorEnterCallback().
+// 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).
+// 2020-01-17: Inputs: Disable error callback while assigning mouse cursors because some X11 setup don't have them and it generates errors.
+// 2019-12-05: Inputs: Added support for new mouse cursors added in GLFW 3.4+ (resizing cursors, not allowed cursor).
+// 2019-10-18: Misc: Previously installed user callbacks are now restored on shutdown.
+// 2019-07-21: Inputs: Added mapping for ImGuiKey_KeyPadEnter.

+// 2018-11-30: Misc: Setting up io.BackendPlatformName so it can be displayed in the About Window.
+// 2018-11-07: Inputs: When installing our GLFW callbacks, we save user's previously installed ones - if any - and chain call them.
+// 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.

+// 2018-02-20: Inputs: Added support for mouse cursors (ImGui::GetMouseCursor() value, passed to glfwSetCursor()).
+// 2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.

+// 2018-01-25: Inputs: Added gamepad support if ImGuiConfigFlags_NavEnableGamepad is set.

+// This needs to be used along with a Renderer (e.g. OpenGL3, Vulkan, WebGPU..)
+// (Info: GLFW is a cross-platform general purpose library for handling windows, inputs, OpenGL/Vulkan graphics context creation, etc.)
+
+// Implemented features:
+// [X] Platform: Clipboard support.
+// [X] Platform: Mouse support. Can discriminate Mouse/TouchScreen/Pen (Windows only).
+// [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 GLFW_KEY_* values are obsolete since 1.87 and not supported since 1.91.5]
+// [X] Platform: Gamepad support. Enable with 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad'.
+// [X] Platform: Mouse cursor shape and visibility (ImGuiBackendFlags_HasMouseCursors) with GLFW 3.1+. Resizing cursors requires GLFW 3.4+! Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'.
+// [X] Multiple Dear ImGui contexts support.
+// Missing features or Issues:
+// [ ] Touch events are only correctly identified as Touch on Windows. This create issues with some interactions. GLFW doesn't provide a way to identify touch inputs from mouse inputs, we cannot call io.AddMouseSourceEvent() to identify the source. We provide a Windows-specific workaround.

+// 2022-09-26: Inputs: Renamed ImGuiKey_ModXXX introduced in 1.87 to ImGuiMod_XXX (old names still supported).
+// 2022-01-26: Inputs: replaced short-lived io.AddKeyModsEvent() (added two weeks ago) with io.AddKeyEvent() using ImGuiKey_ModXXX flags. Sorry for the confusion.
+// 2022-01-17: Inputs: calling new io.AddMousePosEvent(), io.AddMouseButtonEvent(), io.AddMouseWheelEvent() API (1.87+).
+// 2022-01-10: Inputs: calling new io.AddKeyEvent(), io.AddKeyModsEvent() + io.SetKeyEventNativeData() API (1.87+). Support for full ImGuiKey range.
+// 2019-04-03: Misc: Renamed imgui_impl_freeglut.cpp/.h to imgui_impl_glut.cpp/.h.
+// 2019-03-25: Misc: Made io.DeltaTime always above zero.
+// 2018-11-30: Misc: Setting up io.BackendPlatformName so it can be displayed in the About Window.

+// (minor and older changes stripped away, please see git history for details)
+// 2025-09-18: Call platform_io.ClearRendererHandlers() on shutdown.
+// 2025-06-11: Added support for ImGuiBackendFlags_RendererHasTextures, for dynamic font atlas. Removed ImGui_ImplMetal_CreateFontsTexture() and ImGui_ImplMetal_DestroyFontsTexture().
+// 2025-02-03: Metal: Crash fix. (#8367)
+// 2024-01-08: Metal: Fixed memory leaks when using metal-cpp (#8276, #8166) or when using multiple contexts (#7419).

+// 2022-01-03: Metal: Ignore ImDrawCmd where ElemCount == 0 (very rare but can technically be manufactured by user code).
+// 2021-12-30: Metal: Added Metal C++ support. Enable with '#define IMGUI_IMPL_METAL_CPP' in your imconfig.h file.
+// 2021-08-24: Metal: Fixed a crash when clipping rect larger than framebuffer is submitted. (#4464)
+// 2021-05-19: Metal: Replaced direct access to ImDrawCmd::TextureId with a call to ImDrawCmd::GetTexID(). (will become a requirement)
+// 2021-02-18: Metal: Change blending equation to preserve alpha in output buffer.
+// 2021-01-25: Metal: Fixed texture storage mode when building on Mac Catalyst.
+// 2019-05-29: Metal: Added support for large mesh (64K+ vertices), enable ImGuiBackendFlags_RendererHasVtxOffset flag.
+// 2019-04-30: Metal: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
+// 2019-02-11: Metal: Projecting clipping rectangles correctly using draw_data->FramebufferScale to allow multi-viewports for retina display.
