Make isotropic antialiasing logic more readable. #2

Currently, pixel shader multiplies sqrt(2) to signed distance and then applies anti aliase by 1.5 pixel. It can make us confused. This patch removes redundant sqrt(2) and then applies anti alias by just 1 pixel.

The visual result is almost same between before and after.
