What I actually want to know is if anyone has had any problems using an
orthographic channel. When I use pfMakeOrthoChan() the frame buffer no
longer clears between frames--I have to do it manually through my draw
callback. Also, my pfEarthSky I've attached to my channel no longer gets
drawn. Does pfEarthSky not work with orthographic channels?
