I hate to be this off-topic... but reverse anti-aliasing would still be anti-aliasing, wouldn't it? I mean, if you reverse-engineer something, you're still engineering... just, backwards. That there is, like, anti-anti-aliasing... or... extra-aliasing.
Funny thing is, from a certain distance at a certain resolution, it actually has the exact opposite effect of anti-aliasing. It doesn't look like gradient colors around a shape. It looks like the shape itself is really jaggy. It looks like a non-AA'd circle at, like, 1.5x zoom. Fascinating.
Alright, I'm done now.
