------- Additional Comments from Simon Fraser (smfr) <simon.fraser at apple.com>
This is phase 1: add variants of the various "absolute repaint" methods that
take a RenderBox container, and compute the repaint rect relative to that. For
now, RenderObject::containerForRepaint() always returns 0, so all repaints are
still root-relative.
