Repaint rect is snapped to integral position which can result in cruft. Use enclosing integral rect for now (until we transition views to device pixel boundaries).

(In reply to comment #3) > (From update of attachment 229101 [details]) > Can you explain in the change log why WK1 is different? It's not clear to me. Done. WK2 has compositing RenderView so RenderLayerBacking takes care of the repaintrects.
