// dear imgui: Renderer Backend for SDL_Renderer for SDL3
// (Requires: SDL 3.0.0+)

// (**IMPORTANT: SDL 3.0.0 is NOT YET RELEASED AND CURRENTLY HAS A FAST CHANGING API. THIS CODE BREAKS OFTEN AS SDL3 CHANGES.**)

// Note how SDL_Renderer is an _optional_ component of SDL3.
// For a multi-platform app consider using e.g. SDL+DirectX on Windows and SDL+OpenGL on Linux/OSX.
// If your application will want to render any non trivial amount of graphics other than UI,
// please be aware that SDL_Renderer currently offers a limited graphic API to the end-user and
// it might be difficult to step out of those boundaries.

// Implemented features:
//  [X] Renderer: User texture binding. Use 'SDL_Texture*' as ImTextureID. Read the FAQ about ImTextureID!
//  [X] Renderer: Large meshes support (64k+ vertices) with 16-bit indices.
// Missing features:
//  [ ] Renderer: Multi-viewport support (multiple windows).

// You can copy and 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.
