// Implemented features:
// [X] Renderer: User texture binding. Use 'LPDIRECT3DTEXTURE9' as ImTextureID. Read the FAQ about ImTextureID!
// [X] Renderer: Large meshes support (64k+ vertices) with 16-bit indices.
// [X] Renderer: IMGUI_USE_BGRA_PACKED_COLOR is supported, as this is the optimal color encoding for DirectX9.
// [X] Renderer: Multi-viewport support (multiple windows). Enable with 'io.ConfigFlags |= ImGuiConfigFlags_ViewportsEnable'.
// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
