// 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.
// For a multi-platform app consider using e.g. SDL+DirectX on Windows and SDL+OpenGL on Linux/OSX.

// 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: Multi-viewport support (multiple windows).
