------- Additional Comments from Dana Jansens <danakj at chromium.org>
Addressed comments. I'm good with nearestAncestorThatMovesPixels(), thanks for
saving me from 10 more characters.

I moved the 'hasFilterThatMovesPixels()' and 'hasFilterThatAffectsOpacity()'
methods from RenderSurfaceChromium and CCRenderSurface into FilterOperations,
so the code only needs to exist once.

Also, rebased to TOT.
