I was experimenting with the new radiosity today and I noticed when I changed
resolutions that the brightness of the scene changed.  I had some lights in the
scene that I commented out so I could test some ambient objects.  At first I
thought the brightness was different because of the different resolutions, but
apparently the radiosity cache file (from when I rendered it with the lights in
the scene) is being kept but is only used at a specific image resolution.  I'm
not sure yet but it sounds like that old global variable bug might have creeped
back in.
