Committing my current work on Anti-Aliasing for the GL plugin. It works, but it's slow, really slow. I got 1-2FPS in JIT with it enabled. Maybe Windows would be faster, I'm not sure. It's highly experimental and shouldn't be used yet, since some games don't work with it. Like Super Smash Brother's Melee in game.
