Currently repaints originating in RenderElement::repaintAfterLayoutIfNeeded() are computing using two rectangles: the clippedOverflowRect, and the outlineBoundsForRepaint. These are computed in two separate ancestor traversals, but we can make things more efficient by computing them at the same time.
