// If you use one of the default imgui_impl_XXXX.cpp rendering backend, they all have comments at the top
// of their respective source file to specify what they expect to be stored in ImTextureID, for example:
// - The imgui_impl_dx11.cpp renderer expect a 'ID3D11ShaderResourceView*' pointer
// - The imgui_impl_opengl3.cpp renderer expect a GLuint OpenGL texture identifier, etc.
// More:
// - If you decided that ImTextureID = MyEngineTexture*, then you can pass your MyEngineTexture* pointers
// to ImGui::Image(), and gather width/height through your own functions, etc.
// - You can use ShowMetricsWindow() to inspect the draw data that are being passed to your renderer,
// it will help you debug issues if you are confused about it.
