// dear imgui: Renderer Backend for SDL_Renderer for SDL2

// (Requires: SDL 2.0.17+)

// Note how SDL_Renderer is an _optional_ component of SDL2.

// 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.

//  [X] Renderer: Expose selected render state for draw callbacks to use. Access in '(ImGui_ImplXXXX_RenderState*)GetPlatformIO().Renderer_RenderState'.

// Missing features:

//  [ ] Renderer: Multi-viewport support (multiple windows).

// 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.
