 // CHANGELOG
 // (minor and older changes stripped away, please see git history for details)
+//  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).

- - Required: uploading the font atlas texture into graphics memory.

  - Required: rendering indexed textured triangles with a clipping rectangle.

 Dear ImGui windows to be seamlessly detached from the main application window. This is achieved using an

 Supporting the multi-viewports feature correctly using 100% of your own abstractions is more difficult
 than supporting single-viewport.
 If you decide to use unmodified imgui_impl_XXXX.cpp files, you can automatically benefit from
 improvements and fixes related to viewports and platform windows without extra work on your side.
+
+### Platform: Implementing your Platform Backend
+
+The Platform backends in impl_impl_XXX.cpp files contain many implementations.
+
+**In your `ImGui_ImplXXX_Init()` function:**
+- You can allocate your backend data and use `io.BackendPlatformUserData` to store/retrieve it later.
+- Set `io.BackendPlatformName` to a name `"imgui_impl_xxxx"` which will be available in e.g. About box.
+- Set `io.BackendPlatformUserData` to your backend data.
+- Set `io.BackendFlags` with supported optional features:
+  - `ImGuiBackendFlags_HasGamepad`: supports gamepad and currently has one connected.
+  - `ImGuiBackendFlags_HasMouseCursors`: supports honoring GetMouseCursor() value to change the OS cursor shape.
+  - `ImGuiBackendFlags_HasSetMousePos`: supports io.WantSetMousePos requests to reposition the OS mouse position (only used if io.ConfigNavMoveSetMousePos is set).
+  - `ImGuiBackendFlags_PlatformHasViewports` supports multiple viewports. (multi-viewports only)
+  - `ImGuiBackendFlags_HasMouseHoveredViewport` supports calling io.AddMouseViewportEvent() with the viewport under the mouse. IF POSSIBLE, ignore viewports with the ImGuiViewportFlags_NoInputs flag. If this cannot be done, Dear ImGui needs to use a flawed heuristic to find the viewport under mouse position, as it doesn't know about foreign windows. (multi-viewports only)
+
+**In your `ImGui_ImplXXX_NewFrame()` function:**
+- Set `io.DeltaTime` to the time elapsed (in seconds) since last frame.
+- Set `io.DisplaySize` to your window size.
+- Set `io.DisplayFrameBufferSize` to your window pixel density (macOS/iOS only).
+- Update mouse cursor shape is supported.
+
+**In your `ImGui_ImplXXX_NewFrame()` function or event handlers:**
+- **Mouse Support**
+  - Use `io.AddMousePosEvent()`, `io.AddMouseButtonEvent()`, `io.AddMouseWheelEvent()` to pass mouse events.
+  - Use `io.AddMouseSourceEvent()` if you are able to distinguish Mouse from TouchScreen from Pen inputs. TouchScreen and Pen inputs requires different logic for some Dear ImGui features.
+  - Use `io.AddMouseViewportEvent()` to specify which viewport/OS window is being hovered by the mouse. Read instructions carefully as this is not as simple as it seems! (multi-viewports only)
+- **Keyboard Support**
+  - Use `io.AddKeyEvent()` to pass key events.
+  - Use `io.AddInputCharacter()` to pass text/character events.
+- **Gamepad Support**
+  - Use `io.AddKeyEvent()` and `io.AddKeyAnalogEvent()` to pass gamepad events, using `ImGuiKey_GamepadXXX` values.
+- **Miscellaneous**
+  - Clipboard Support: setup `Platform_GetClipboardTextFn()`, `Platform_SetClipboardTextFn()` handlers in `ImGuiPlatformIO`.
+  - Open in Shell support: setup `Platform_OpenInShellFn()` handler in `ImGuiPlatformIO`.
+  - IME Support: setup `Platform_SetImeDataFn()` handler in `ImGuiPlatformIO`.
+  - Use `io.AddFocusEvent()` to notify when application window gets focused/unfocused.
+- **Multi-viewport Support**
+  - Update monitor list if supported.
+  - Setup all required handlers in `ImGuiPlatformIO` to create/destroy/move/resize/title/focus/etc. windows.
+
+### Rendering: Implementing your RenderDrawData function
+
+Note: set `ImGuiBackendFlags_RendererHasVtxOffset` to signify your backend can handle rendering with a vertex offset (`ImDrawCmd::VtxOffset` field).
+Otherwise, rendering will be limited to 64K vertices per window, which may be limiting for advanced plot.
+As an alternative, you may also use `#define ImDrawIdx unsigned int` in your `imconfig.h` file to support 32-bit indices.

+### Rendering: Adding support for `ImGuiBackendFlags_RendererHasTextures` (1.92+)
+
+Version [1.92.0](https://github.com/ocornut/imgui/releases/tag/v1.92.0) (June 2025), added texture support in Rendering Backends, which is the backbone for supporting dynamic font scaling among other things.
+
+**In order to move forward and take advantage of all new features, support for `ImGuiBackendFlags_RendererHasTextures` will likely be REQUIRED for all backends before June 2026.**
+
+`ImFontAtlas` functions such as `Build()`, `GetTexDataAsRGBA32()`, `GetTexDataAsAlpha8()`, `SetTexID()`, `IsBuilt()` were obsoleted in favor if iterating a `Textures[]` array and updating their state when requested by Dear ImGui.

+
+**Instructions:**
+
+- Set `ImGuiBackendFlags_RendererHasTextures` to signify your backend can handle the feature.
+- During rendering, e.g. in your RenderDrawData function, iterate `ImDrawData->Textures` array and process all textures.
+- During shutdown, iterate the `ImGui::GetPlatformIO().Textures` and destroy all textures.
+- (Both arrays are `ImVector<ImTextureData*>`. They are only in different location because: to allow advanced users to perform multi-threaded rendering, we store a pointer to the texture list in ImDrawData, with the aim that multi-threaded rendering users replace it with their own pointer.)
+
+Pseudo-code for processing a texture:
+```cpp
+if (draw_data->Textures != nullptr)
+    for (ImTextureData* tex : *draw_data->Textures)
+        if (tex->Status != ImTextureStatus_OK)
+            MyImGuiBackend_UpdateTexture(tex);
+```
+```cpp
+void MyImGuiBackend_UpdateTexture(ImTextureData* tex)
+{
+    if (tex->Status == ImTextureStatus_WantCreate)
+    {
+        // Create texture based on tex->Width, tex->Height.
+        // - Most backends only support tex->Format == ImTextureFormat_RGBA32.
+        // - Backends for particularly memory constrainted platforms may support tex->Format == ImTextureFormat_Alpha8.
+
+        // Upload all texture pixels
+        // - Read from our CPU-side copy of the texture and copy to your graphics API.
+        // - Use tex->Width, tex->Height, tex->GetPixels(), tex->GetPixelsAt(), tex->GetPitch() as needed.
+
+        // Store your data, and acknowledge creation.
+        tex->SetTexID(xxxx); // Specify backend-specific ImTextureID identifier which will be stored in ImDrawCmd.
+        tex->SetStatus(ImTextureStatus_OK);
+        tex->BackendUserData = xxxx; // Store more backend data if needed (most backend allocate a small texture to store data in there)
+    }
+    if (tex->Status == ImTextureStatus_WantUpdates)
+    {
+        // Upload a rectangle of pixels to the existing texture
+        // - We only ever write to textures regions which have never been used before!
+        // - Use tex->TexID or tex->BackendUserData to retrieve your stored data.
+        // - Use tex->UpdateRect.x/y, tex->UpdateRect.w/h to obtain the block position and size.
+        //   - Use tex->Updates[] to obtain individual sub-regions within tex->UpdateRect. Not recommended.
+        // - Read from our CPU-side copy of the texture and copy to your graphics API.
+        // - Use tex->Width, tex->Height, tex->GetPixels(), tex->GetPixelsAt(), tex->GetPitch() as needed.
+
+        // Acknowledge update
+        tex->SetStatus(ImTextureStatus_OK);
+    }
+    if (tex->Status == ImTextureStatus_WantDestroy && tex->UnusedFrames > 0)
+    {
+        // If you use staged rendering and have in-flight renders, changed tex->UnusedFrames > 0 check to higher count as needed e.g. > 2
+
+        // Destroy texture
+        // - Use tex->TexID or tex->BackendUserData to retrieve your stored data.
+        // - Destroy texture in your graphics API.
+
+        // Acknowledge destruction
+        tex->SetTexID(ImTextureID_Invalid);
+        tex->SetStatus(ImTextureStatus_Destroyed);
+    }
+}

 - Article: [How To Ask Good Questions](https://bit.ly/3nwRnx1).
 - **PLEASE DO FILL THE REQUESTED NEW ISSUE TEMPLATE.** Including Dear ImGui version number, branch name, platform/renderer back-ends (imgui_impl_XXX files), operating system.
 - **Try to be explicit with your GOALS, your EXPECTATIONS and what you have tried**.  Be mindful of [The XY Problem](http://xyproblem.info/). What you have in mind or in your code is not obvious to other people. People frequently discuss problems and suggest incorrect solutions without first clarifying their goals. When requesting a new feature, please describe the usage context (how you intend to use it, why you need it, etc.). If you tried something and it failed, show us what you tried.
+- **Please INCLUDE CODE. Provide a Minimal, Complete, and Verifiable Example ([MCVE](https://stackoverflow.com/help/mcve)) to demonstrate your problem**. An ideal submission includes a small piece of code that anyone can paste into one of the examples applications (examples/../main.cpp) or 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.
 - **Attach screenshots (or GIF/video) to clarify the context**. They often convey useful information that is omitted by the description. You can drag pictures/files in the message edit box. Avoid using 3rd party image hosting services, prefer the long-term longevity of GitHub attachments (you can drag pictures into your post). On Windows, you can use [ScreenToGif](https://www.screentogif.com/) to easily capture .gif files.
 - **If you are discussing an assert or a crash, please provide a debugger callstack**. Never state "it crashes" without additional information. If you don't know how to use a debugger and retrieve a callstack, learning about it will be useful.
 - **Please make sure that your project has asserts enabled.** Calls to IM_ASSERT() are scattered in the code to help catch common issues. When an assert is triggered read the comments around it. By default IM_ASSERT() calls the standard assert() function. To verify that your asserts are enabled, add the line `IM_ASSERT(false);` in your main() function. Your application should display an error message and abort. If your application doesn't report an error, your asserts are disabled.

 ## How to open a Pull Request
 
 - **Please understand that by submitting a PR you are also submitting a request for the maintainer to review your code and then take over its maintenance.** PR should be crafted both in the interest of the end-users and also to ease the maintainer into understanding and accepting it.
-- Many PRs are useful to demonstrate a need and a possible solution but aren't adequate for merging (causing other issues, not seeing other aspects of the big picture, etc.). In doubt, don't hesitate to push a PR because that is always the first step toward finding the mergeable solution! Even if a PR stays unmerged for a long time, its presence can be useful for other users and helps toward finding a general solution.

Even if a PR stays unmerged for a long time, its presence can be useful for other users and helps toward finding a general solution.
 - **When adding a feature,** please describe the usage context (how you intend to use it, why you need it, etc.). Be mindful of [The XY Problem](http://xyproblem.info/).
 - **When fixing a warning or compilation problem,** please post the compiler log and specify the compiler version and platform you are using.
 - **Attach screenshots (or GIF/video) to clarify the context and demonstrate the feature at a glance.** You can drag pictures/files in the message edit box. Prefer the long-term longevity of GitHub attachments over 3rd party hosting (you can drag pictures into your post).
 - **Make sure your code follows the coding style already used in the codebase:** 4 spaces indentations (no tabs), `local_variable`, `FunctionName()`, `MemberName`, `// Text Comment`, `//CodeComment();`, C-style casts, etc.. We don't use modern C++ idioms and tend to use only a minimum of C++11 features. The applications under examples/ are generally less consistent because they sometimes try to mimic the coding style often adopted by a certain ecosystem (e.g. DirectX-related code tend to use the style of their sample).
 - **Make sure you create a branch dedicated to the pull request**. In Git, 1 PR is associated to 1 branch. If you keep pushing to the same branch after you submitted the PR, your new commits will appear in the PR (we can still cherry-pick individual commits).

 **Note:** The `io.WantCaptureMouse` is more correct that any manual attempt to "check if the mouse is hovering a window" (don't do that!). It handles mouse dragging correctly (both dragging that started over your application or over a Dear ImGui window) and handle e.g. popup and modal windows blocking inputs.
 
-**Note:** Those flags are updated by `ImGui::NewFrame()`. However it is generally more correct and easier that you poll flags from the previous frame, then submit your inputs, then call `NewFrame()`. If you attempt to do the opposite (which is generally harder) you are likely going to submit your inputs after `NewFrame()`, and therefore too late.

 **Note:** Text input widget releases focus on the "KeyDown" event of the Return key, so the subsequent "KeyUp" event that your application receive will typically have `io.WantCaptureKeyboard == false`. Depending on your application logic it may or not be inconvenient to receive that KeyUp event.

+- Loading image files from the disk and turning them into a texture is not within the scope of Dear ImGui (for a good reason), but the examples linked above may be useful references.
+
+**Details:**
+
+1.92 introduced `ImTextureRef` in June 2025.
+- All drawing functions using `ImTextureID` were changed to use `ImTextureRef`.
+- You can trivially create a `ImTextureRef` from a `ImTextureID`.
+- **If you use Image functions with textures that you have loaded/created yourself, you will mostly likely only ever store/manipulate `ImTextureID` and then pass them as `ImTextureRef`.**
+- You only NEED to manipulate `ImTextureRef` when dealing with textures managed by the backend itself, aka mainly the atlas texture for now.
+- We intentionally do not provide an implicit `ImTextureRef` -> `ImTextureID` cast operator because it is technically lossy to convert ImTextureRef to ImTextureID before rendering.
+
+**ImTextureID = backend specific, low-level identifier for a texture uploaded in GPU/graphics system.**
+```cpp
+#ifndef ImTextureID
+typedef ImU64 ImTextureID;  // Default: store up to 64-bits (any pointer or integer). A majority of backends are ok with that.
+#endif
+```
+- When a Rendered Backend creates a texture, it store its native identifier into a ImTextureID value (e.g. Used by DX11 backend to a `ID3D11ShaderResourceView*`; Used by OpenGL backends to store `GLuint`; Used by SDLGPU backend to store a `SDL_GPUTextureSamplerBinding*`, etc.).
+- User may submit their own textures to e.g. `ImGui::Image()` function by passing this value.
+- During the rendering loop, the Renderer Backend retrieve the ImTextureID, which stored inside a ImTextureRef, which is stored inside ImDrawCmd.
+- Compile-time type configuration:
+  - To use something other than a 64-bit value: add '#define ImTextureID MyTextureType*' in your imconfig.h file.
+  - This can be whatever to you want it to be! read the FAQ entry about textures for details.
+  - You may decide to store a higher-level structure containing texture, sampler, shader etc. with various constructors if you like. You will need to implement ==/!= operators.
+
+**ImTextureRef = higher-level identifier for a texture.**
+```cpp
+// Store a ImTextureID _or_ a ImTextureData*.
+struct ImTextureRef
+{
+    ImTextureRef()                          { _TexData = NULL; _TexID = ImTextureID_Invalid; }
+    ImTextureRef(ImTextureID tex_id)        { _TexData = NULL; _TexID = tex_id; }
+    inline ImTextureID  GetTexID() const    { return _TexData ? _TexData->TexID : _TexID; }
+
+    // Members (either are set, never both!)
+    ImTextureData*      _TexData;           //      A texture, generally owned by a ImFontAtlas. Will convert to ImTextureID during render loop, after texture has been uploaded.
+    ImTextureID         _TexID;             // _OR_ Low-level backend texture identifier, if already uploaded or created by user/app. Generally provided to e.g. ImGui::Image() calls.
+};
+```
+- The identifier is valid even before the texture has been uploaded to the GPU/graphics system.
+- This is what gets passed to functions such as `ImGui::Image()`, `ImDrawList::AddImage()`.
+- This is what gets stored in draw commands (`ImDrawCmd`) to identify a texture during rendering.
+ - When a texture is created by user code (e.g. custom images), we directly store the low-level `ImTextureID`.
+   - Because of this, when displaying your own texture you are likely to ever only manage ImTextureID values on your side.
+ - When a texture is created by the backend, we store a `ImTextureData*` which becomes an indirection to extract the `ImTextureID` value during rendering, after texture upload has happened.
+ - To create a `ImTextureRef` from a `ImTextureData*` you can use `ImTextureData::GetTexRef()`.
+   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`.
+ - Binding generators for languages such as C (which don't have constructors), should provide a helper, e.g. `inline ImTextureRef ImTextureRefFromID(ImTextureID tex_id) { ImTextureRef tex_ref = { ._TexData = NULL, .TexID = tex_id }; return tex_ref; }`
 
 **Please read documentations or tutorials on your graphics API to understand how to display textures on the screen before moving onward.**
 
 Long explanation:
 - Dear ImGui's job is to create "meshes", defined in a renderer-agnostic format made of draw commands and vertices. At the end of the frame, those meshes (ImDrawList) will be displayed by your rendering function. They are made up of textured polygons and the code to render them is generally fairly short (a few dozen lines). In the examples/ folder, we provide functions for popular graphics APIs (OpenGL, DirectX, etc.).
 - Each rendering function decides on a data type to represent "textures". The concept of what is a "texture" is entirely tied to your underlying engine/graphics API.
- We carry the information to identify a "texture" in the ImTextureID type.
+We carry the information to identify a "texture" in the ImTextureID type, which itself tends to be stored inside a ImTextureRef.
-ImTextureID is nothing more than a void*, aka 4/8 bytes worth of data: just enough to store one pointer or integer of your choice.
+ImTextureID default to ImU64 aka 8 bytes worth of data: just enough to store one pointer or integer of your choice.

 - In the [examples/](https://github.com/ocornut/imgui/tree/master/examples) backends, for each graphics API we decided on a type that is likely to be a good representation for specifying an image from the end-user perspective. This is what the _examples_ rendering functions are using:
 ```cpp

 ### Q: How should I handle DPI in my application?
 
-The short answer is: obtain the desired DPI scale, load your fonts resized with that scale (always round down fonts size to the nearest integer), and scale your Style structure accordingly using `style.ScaleAllSizes()`.
+Since 1.92 (June 2025) fonts may be dynamically used at any size.
 
-Your application may want to detect DPI change and reload the fonts and reset style between frames.
+**Scaling fonts**
 
-Your ui code  should avoid using hardcoded constants for size and positioning. Prefer to express values as multiple of reference values such as `ImGui::GetFontSize()` or `ImGui::GetFrameHeight()`. So e.g. instead of seeing a hardcoded height of 500 for a given item/window, you may want to use `30*ImGui::GetFontSize()` instead.
+To change font size:
+```cpp
+ImGui::PushFont(NULL, 42.0f);
+```
+To change font and font size:
+```cpp
+ImGui::PushFont(new_font, 42.0f);
+```
+To scale all fonts:
+```cpp
+style.FontScaleDpi = 2.0f;
+```
+In `docking` branch or with multi-viewports:
+```cpp
+io.ConfigDpiScaleFonts = true;          // [Experimental] Automatically overwrite style.FontScaleDpi in Begin() when Monitor DPI changes. This will scale fonts but _NOT_ scale sizes/padding for now.
+io.ConfigDpiScaleViewports = true;      // [Experimental] Scale Dear ImGui and Platform Windows when Monitor DPI changes.
+```
 
-Down the line Dear ImGui will provide a variety of standardized reference values to facilitate using this.
+**Scaling style** (paddings, spacings, thicknesses)
 
-Applications in the `examples/` folder are not DPI aware partly because they are unable to load a custom font from the file-system (may change that in the future).
+This is still massively work in progress, expect turbulence.
+Style values are currently not easily scalable dynamically.
+For single viewport application you can call once:
+```cpp
+style.ScaleAllSizes(factor); // call once!
+```
+If you need to change the scaling factor, it is currently most practical to reset the style and call this again with a new value.
 
-The reason DPI is not auto-magically solved in stock examples is that we don't yet have a satisfying solution for the "multi-dpi" problem (using the `docking` branch: when multiple viewport windows are over multiple monitors using different DPI scales). The current way to handle this on the application side is:
+Your UI code should avoid using hardcoded constants for size and positioning. Prefer to express values as multiple of reference values such as `ImGui::GetFontSize()` or `ImGui::GetFrameHeight()`. So e.g. instead of seeing a hardcoded height of 500 for a given item/window, you may want to use `30*ImGui::GetFontSize()` instead.
-- Create and maintain one font atlas per active DPI scale (e.g. by iterating `platform_io.Monitors[]` before `NewFrame()`).
-- Hook `platform_io.OnChangedViewport()` to detect when a `Begin()` call makes a Dear ImGui window change monitor (and therefore DPI).
-- In the hook: swap atlas, swap style with correctly sized one, and remap the current font from one atlas to the other (you may need to maintain a remapping table of your fonts at varying DPI scales).
 
-This approach is relatively easy and functional but comes with two issues:
+Down the line Dear ImGui will provide a variety of standardized reference values to facilitate using this. This is expected to happen during subsequent 1.92.x releases.
-- It's not possibly to reliably size or position a window ahead of `Begin()` without knowing on which monitor it'll land.
-- Style override may be lost during the `Begin()` call crossing monitor boundaries. You may need to do some custom scaling mumbo-jumbo if you want your `OnChangedViewport()` handler to preserve style overrides.
 
-Please note that if you are not using multi-viewports with multi-monitors using different DPI scales, you can ignore that and use the simpler technique recommended at the top.
+Applications in the `examples/` folder are partly DPI aware but they are unable to load a custom font from the file-system, so they look ugly (may change that in the future).
 
-On Windows, in addition to scaling the font size (make sure to round to an integer) and using `style.ScaleAllSizes()`, you will need to inform Windows that your application is DPI aware. If this is not done, Windows will scale the application window and the UI text will be blurry. Potential solutions to indicate DPI awareness on Windows are:

+
+This was a previous  constraint of Dear ImGui (lifted in 1.92): when loading a font you need to specify which characters glyphs to load.
 All loaded fonts glyphs are rendered into a single texture atlas ahead of time. Calling either of `io.Fonts->GetTexDataAsAlpha8()`, `io.Fonts->GetTexDataAsRGBA32()` or `io.Fonts->Build()` will build the atlas. This is generally called by the Renderer backend, e.g. `ImGui_ImplDX11_NewFrame()` calls it. **If you use custom glyphs ranges, make sure the array is persistent** and available during the calls to `GetTexDataAsAlpha8()/GetTexDataAsRGBA32()/Build()`.
 
 ### (4) Font atlas texture fails to upload to GPU.
 
-This is often of byproduct of point 3. If you have large number of glyphs or multiple fonts, the texture may become too big for your graphics API. **The typical result of failing to upload a texture is if every glyph or everything appears as empty black or white rectangle.** Mind the fact that some graphics drivers have texture size limitation. If you are building a PC application, mind the fact that your users may use hardware with lower limitations than yours.

+- You may reduce oversampling, e.g. `font_config.OversampleH = 1`, this will half your texture size for a quality loss.
   Note that while OversampleH = 2 looks visibly very close to 3 in most situations, with OversampleH = 1 the quality drop will be noticeable. Read about oversampling [here](https://github.com/nothings/stb/blob/master/tests/oversample).
 - Reduce glyphs ranges by calculating them from source localization data.
   You can use the `ImFontGlyphRangesBuilder` for this purpose and rebuilding your atlas between frames when new characters are needed. This will be the biggest win!
 - Set `io.Fonts.Flags |= ImFontAtlasFlags_NoPowerOfTwoHeight;` to disable rounding the texture height to the next power of two.
-- Set `io.Fonts.TexDesiredWidth` to specify a texture width to reduce maximum texture height (see comment in `ImFontAtlas::Build()` function).

+## New! Dynamic Fonts system in 1.92 (June 2025)
+
+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.
+- 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.

 ### The Pitch
 
 Dear ImGui is a **bloat-free graphical user interface library for C++**. It outputs optimized vertex buffers that you can render anytime in your 3D-pipeline-enabled application. It is fast, portable, renderer agnostic, and self-contained (no external dependencies).
 
-Dear ImGui is designed to **enable fast iterations** and to **empower programmers** to create **content creation tools and visualization / debug tools** (as opposed to UI for the average end-user). It favors simplicity and productivity toward this goal and lacks certain features commonly found in more high-level libraries.
+Dear ImGui is designed to **enable fast iterations** and to **empower programmers** to create **content creation tools and visualization / debug tools** (as opposed to UI for the average end-user). It favors simplicity and productivity toward this goal and lacks certain features commonly found in more high-level libraries. Among other things, full internationalization (right-to-left text, bidirectional text, text shaping etc.) and accessibility features are not supported.
 
 Dear ImGui is particularly suited to integration in game engines (for tooling), real-time 3D applications, fullscreen applications, embedded applications, or any applications on console platforms where operating system features are non-standard.
 
  - Minimize state synchronization.
- - Minimize state storage on user side.
+ - Minimize UI-related state storage on user side.
  - Minimize setup and maintenance.
  - Easy to use to create dynamic UI which are the reflection of a dynamic data set.
  - Easy to use to create code-driven and data-driven tools.

 ### Usage
 
-**The core of Dear ImGui is self-contained within a few platform-agnostic files** which you can easily compile in your application/engine. They are all the files in the root folder of the repository (imgui*.cpp, imgui*.h). **No specific build process is required**. You can add the .cpp files into your existing project. See [Getting Started](https://github.com/ocornut/imgui/wiki/Getting-Started).

 Calling the `ImGui::ShowDemoWindow()` function will create a demo window showcasing a variety of features and examples. The code is always available for reference in `imgui_demo.cpp`. [Here's how the demo looks](https://raw.githubusercontent.com/wiki/ocornut/imgui/web/v167/v167-misc.png).

 The demo applications are not DPI aware so expect some blurriness on a 4K screen. For DPI awareness in your application, you can load/reload your font at a different scale and scale your style with `style.ScaleAllSizes()` (see [FAQ](https://www.dearimgui.com/faq)).

+### Getting Started & Integration
+
+See the [Getting Started](https://github.com/ocornut/imgui/wiki/Getting-Started) guide for details.
 
 On most platforms and when using C++, **you should be able to use a combination of the [imgui_impl_xxxx](https://github.com/ocornut/imgui/tree/master/backends) backends without modification** (e.g. `imgui_impl_win32.cpp` + `imgui_impl_dx11.cpp`). If your engine supports multiple platforms, consider using more imgui_impl_xxxx files instead of rewriting them: this will be less work for you, and you can get Dear ImGui running immediately. You can _later_ decide to rewrite a custom backend using your custom engine functions if you wish so.
 
-See [Getting Started](https://github.com/ocornut/imgui/wiki/Getting-Started). Integrating Dear ImGui within your custom engine is a matter of 1) wiring mouse/keyboard/gamepad inputs 2) uploading a texture to your GPU/render engine 3) providing a render function that can bind textures and render textured triangles, which is essentially what Backends are doing. The [examples/](https://github.com/ocornut/imgui/tree/master/examples) folder is populated with applications doing just that: setting up a window and using backends. If you follow [Getting Started](https://github.com/ocornut/imgui/wiki/Getting-Started) it should in theory takes you less than an hour to integrate Dear ImGui.  **Make sure to spend time reading the [FAQ](https://www.dearimgui.com/faq), comments, and the examples applications!**

-We occasionally tag [Releases](https://github.com/ocornut/imgui/releases) (with nice releases notes) but it is generally safe and recommended to sync to latest `master` or `docking` branch. The library is fairly stable and regressions tend to be fixed fast when reported.

This branch is kept in sync with master regularly.

 Omar: "I first discovered the IMGUI paradigm at [Q-Games](https://www.q-games.com) where Atman Binstock had dropped his own simple implementation in the codebase, which I spent quite some time improving and thinking about. It turned out that Atman was exposed to the concept directly by working with Casey. When I moved to Media Molecule I rewrote a new library trying to overcome the flaws and limitations of the first one I've worked with. It became this library and since then I have spent an unreasonable amount of time iterating and improving it."
