1 // dear imgui: Renderer Backend for SDL_Renderer 2 // (Requires: SDL 2.0.17+) 3 4 // Important to understand: SDL_Renderer is an _optional_ component of SDL. We do not recommend you use SDL_Renderer 5 // because it provide a rather limited API to the end-user. We provide this backend for the sake of completeness. 6 // For a multi-platform app consider using e.g. SDL+DirectX on Windows and SDL+OpenGL on Linux/OSX. 7 8 // Implemented features: 9 // [X] Renderer: User texture binding. Use 'SDL_Texture*' as ImTextureID.
