text: // dear imgui: Renderer for DirectX9
  // This needs to be used along with a Platform Binding (e.g. Win32)
  
  // Implemented features:
  //  [X] Renderer: User texture binding. Use 'LPDIRECT3DTEXTURE9' as ImTextureID. Read the FAQ about ImTextureID!
  //  [X] Renderer: Multi-viewport support. Enable with 'io.ConfigFlags |= ImGuiConfigFlags_ViewportsEnable'.
  //  [X] Renderer: Support for large meshes (64k+ vertices) with 16-bits indices.
  
  // You can copy and use unmodified imgui_impl_* files in your project. See main.cpp for an example of using this.
  // If you are new to dear imgui, read examples/README.txt and read the documentation at the top of imgui.cpp.
