// ImGui Win32 + DirectX12 binding
// In this binding, ImTextureID is used to store a 'D3D12_GPU_DESCRIPTOR_HANDLE' texture identifier. Read the FAQ about ImTextureID in imgui.cpp.
// FIXME: 64-bit only for now! (Because sizeof(ImTextureId) == sizeof(void*))
// Implemented features:
// [X] User texture binding. Use 'D3D12_GPU_DESCRIPTOR_HANDLE' as ImTextureID. Read the FAQ about ImTextureID in imgui.cpp.
// You can copy and use unmodified imgui_impl_* files in your project. See main.cpp for an example of using this.
// If you use this binding you'll need to call 4 functions: ImGui_ImplXXXX_Init(), ImGui_ImplXXXX_NewFrame(), ImGui::Render() and ImGui_ImplXXXX_Shutdown().
