// ImDrawIdx: vertex index. [Compile-time configurable type]
// - To use 16-bit indices + allow large meshes: backend need to set 'io.BackendFlags |= ImGuiBackendFlags_RendererHasVtxOffset' and handle ImDrawCmd::VtxOffset (recommended).
// - To use 32-bit indices: override with '#define ImDrawIdx unsigned int' in your imconfig.h file.
#ifndef ImDrawIdx
typedef unsigned short ImDrawIdx;  // Default: 16-bit (for maximum compatibility with renderer backends)
#endif // #ifndef ImDrawIdx
// This needs to be used along with a Platform Binding (e.g. GLFW, SDL2, SDL3)
// (Please note that WebGPU is a recent API, may not be supported by all browser, and its ecosystem is generally a mess)

// When targeting native platforms:
//  - One of IMGUI_IMPL_WEBGPU_BACKEND_DAWN, IMGUI_IMPL_WEBGPU_BACKEND_WGPU or IMGUI_IMPL_WEBGPU_BACKEND_WGVK *must* be provided.
// When targeting Emscripten:
//  - We now defaults to IMGUI_IMPL_WEBGPU_BACKEND_DAWN and requires Emscripten 4.0.10+, which correspond to using Emscripten '--use-port=emdawnwebgpu'.
//  - Emscripten < 4.0.10 is not supported anymore (old '-sUSE_WEBGPU=1' option).
//  - We can still define IMGUI_IMPL_WEBGPU_BACKEND_WGPU to use Emscripten '-s USE_WEBGPU=1' which is marked as obsolete by Emscripten.
// Add #define to your imconfig.h file, or as a compilation flag in your build system.
// This requirement may be removed once WebGPU stabilizes and backends converge on a unified interface.
//#define IMGUI_IMPL_WEBGPU_BACKEND_DAWN
//#define IMGUI_IMPL_WEBGPU_BACKEND_WGPU
//#define IMGUI_IMPL_WEBGPU_BACKEND_WGVK

// Implemented features:
//  [X] Renderer: User texture binding. Use 'WGPUTextureView' as ImTextureID. Read the FAQ about ImTextureID/ImTextureRef!
//  [X] Renderer: Large meshes support (64k+ vertices) even with 16-bit indices (ImGuiBackendFlags_RendererHasVtxOffset).
//  [X] Renderer: Expose selected render state for draw callbacks to use. Access in '(ImGui_ImplXXXX_RenderState*)GetPlatformIO().Renderer_RenderState'.
//  [X] Renderer: Texture updates support for dynamic font system (ImGuiBackendFlags_RendererHasTextures).
// Missing features or Issues:
//  [ ] Renderer: Multi-viewport support (multiple windows), useful for desktop.

// 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.
