Revert 261000 "Re-raster GPU-rasterized layers during scale animations"
This reverts http://crrev.com/
216313007.
Re-rastering a layer with text during a scale animation can cause
many texture uploads during the animation (as new glyphs are generated
at each scale).
To re-enable this behavior in the future, we need to either make it
dependent on distance-field fonts, or we need a way to reuse glyphs
during scale animations (allowing text to become slightly blurry rather
than generating new glyphs every frame).
