GLSL Antialiasing

I finally got off my ass and picked up the GLSL Orange book, and am beginning to add some niceties to the shaders for Beta 2, like antialiasing for some of the procedural textures for effects. However, I am having a hard time figuring out how to antialias shaders like repos, which offset texture coordinates. Now that I have my free time back, I can get back to doing some work!
