Optimized antialiasing fragment shaders by computing quad edge distance per vertex instead of per pixel.
In particular for tile AA fragment shaders:
before:
vs: 26 cycles
fs: 12 cycles
after:
vs: 47 cycles
fs: 6 cycles
which is a good performance win given there are only 4 vertices but ~64k pixels per tile.
