Reland "Remove interpolants are inaccurate workaround for Adreno 3xx."
This is a reland of a7a278205bb040061cb4ba46839efe18635c7edc
Clean reland. Change to Chrome screenshot unit test has stuck. The previous
revert of that was the reason this had to be reverted.
Original change's description:
> Remove interpolants are inaccurate workaround for Adreno 3xx.
>
> The chrome screenshot unit test that led to adding this workaround has
> been adjusted to avoid testing AA edges of rendered rectangles. We're
> accepting the inaccuracy in favor of increased performance.
