Reland Paint solid color backgrounds which are equivalent to locally attached into scrolling contents layer (patchset #9 id:160001 of https://codereview.chromium.org/2264663002/ )

If we have a solid color background whose bounds / visible rect is equivalent to the padding-box we can treat it as locally attached and paint it into the scrolling contents layer. This enables composited scrolling with sub-pixel text anti-aliasing.
