// Draw callbacks for advanced uses.
// NB- You most likely do NOT need to use draw callbacks just to create your own widget or customized UI rendering (you can poke into the draw list for that)
// Draw callback may be useful for example, A) Change your GPU render state, B) render a complex 3D scene inside a UI element (without an intermediate texture/render target), etc.
