Revert "Improve quad edges' smoothness in non-AA cases"

This reverts commit d4ed326d6f3704995b0e91292bf2c87e9d36bb14.

Reason for revert: reverting temporarily to get us rolling into Chrome again.

Must be this CL right?

Original change's description:
> Improve quad edges' smoothness in non-AA cases
> 
> Previously, non-AA quad edges only have an accuracy about 1/2 pixel
> (while the AA quad edges have an accuracy about 1/8 pixel).  Now, we
> increase non-AA quad edges' accuracy to 1/8 pixel as well.
> 
> The difference is very significant for rotating non-AA filled circles.
> For example, run `./out/Debug/SampleApp --slide GM:fillcircle` with AA
> turned off (by pressing b).
> 
> The benchmark added reveals that increasing quad accuracy from 1/2 to
> 1/8 doesn't affect the performance significantly. The following is the
> 1/2-accuracy performance versus 1/8-accuracy performance:
