Add another render pass ESNRP_GUI which is drawn last and is p.E. useful for rendering gui nodes in the scenemanager.

Browse Source 
UI and scenenodes are often connected. And while it was possible to work around this already by using custom draw functions
or deriving from gui and scene-nodes at the same time, it did already lead a few times to uglier code for me. 
So I guess adding one more pass to the engine has it's uses.
