I really think it does. But nice rectangles are a special case. Gnash
mostly has to deal with rotated shapes or even irregular shapes
(circles, for example).
I agree having specialised code for perfect rectangles would speed up
rendering, but they are a rarity, and anyway not worth to be
specialised.
AGG internally does some voodoo stuff with it's vectors so it may even
come close to block drawing in a more general manner. This is beyond
my understanding, AGG internals are too complicated for me ;)
After all, according to the author, the strengths of AGG are in it's
"vector pipeline" we don't use at all (probably we do implicitly).
