You should only call it from the draw process or while the process calling
it has an open display list. It's safe to call pfOverride from any draw
(post, pre) callback but it looks like calling it from any cull callback
will not, and certainly not from the app.
The short version of how pfOverride works is:
if(display list is open)
queue override on displaylist
else
execute override immediately.
Calling pfOverride outside of draw probably won't do anything horrible but
it may corrupt state for one frame.
