Increase the % coverage for coalescing for paint rects.
The previous number was made up, and so is my number, it's just a larger made
up number.
We want this number to be as high as possible (less coalescing) without causing
page cycler regressions. This means less painting and gives some other
optimizations like the always-on-top Pepper plugin optimization to kick in more
often.
If this causes a PLT regression, it should be reverted.
TEST=page cycler
BUG=none
