It should be mentioned that there is a tradeoff here:  better anti-aliasing
can give satisfactory results with lower resolution.  Many of the people
doing movie animation will tell you that, say, 2K resolution is vital.
The computer graphics group at Lucasfilm consistently produces high-quality
images using only TV resolution, by doing *good* anti-aliasing.  Likewise
for the people at NYIT.  It should be understood that this sort of anti-
aliasing is the kind that eats Crays alive, at least when done in bulk.
