I suppose it doesn't matter much, since one can always increase or decrease
the resolution by 1, but it would make more sense to me to have 20*20*2
triangles. If nothing else, I think this would simplify the macros a little
bit. (Loop i from 0 to width and j from 0 to height, taking samples at
(i/width, j/height).)
