// dear imgui: Renderer Backend for SDL_Renderer
// (Requires: SDL 2.0.17+)
// Important to understand: SDL_Renderer is an _optional_ component of SDL. We do not recommend you use SDL_Renderer
// because it provide a rather limited API to the end-user. We provide this backend for the sake of completeness.
// Important to understand: SDL_Renderer is an _optional_ component of SDL.
// 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 offers a limited graphic API to the end-user and it might
// be difficult to step out of those boundaries.
// However, we understand it is a convenient choice to get an app started easily.
// Implemented features:
// [X] Renderer: User texture binding. Use 'SDL_Texture*' as ImTextureID. Read the FAQ about ImTextureID!
// Missing features:
// [ ] Renderer: Support for large meshes (64k+ vertices) with 16-bit indices.
// [ ] Renderer: Support for large meshes (64k+ vertices) with 16-bit indices (SDL_RenderGeometryRaw() is missing a vertex offset).
// [ ] 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.
