// Implemented features:
// [X] Renderer: User texture binding. Use 'D3D12_GPU_DESCRIPTOR_HANDLE' as ImTextureID. Read the FAQ about ImTextureID!
// [X] Renderer: Support for large meshes (64k+ vertices) with 16-bits indices.
// [X] Renderer: Multi-viewport.
// Missing features, issues:
// [ ] Renderer: Missing multi-viewport support.
// [ ] 64-bit only for now! (Because sizeof(ImTextureId) == sizeof(void*)). See github.com/ocornut/imgui/pull/301
// You can copy and use unmodified imgui_impl_* files in your project. See main.cpp for an example of using this.
