Post Event option for Overlays

An option that would make overlays a lot more useful would be, to add an option to switch to Post-rendering, instead of Pre-rendering. I personally use this for custom boss bars by changing a few characters in the code, and it would be very convenient to just have an option in the element customization window, so that I don't have to re-edit the code if I need to unlock it for any reason.

public static void eventHandler(RenderGuiEvent.Pre event) ---> public static void eventHandler(RenderGuiEvent.Post event)

This seems relatively simple to add, and would be pretty nice to have for custom HUD elements and customization.
