        <rdar://problem/6997929> Assertion at WebCore::RenderLayer::updateClipRects with hardware acceleration

        The updatingControlTints() painting pass goes through compositing layer boundaries,
        so we need to ensure we don't cache clip rects computed with the wrong root by
        setting temporaryClipRects to true.

        * rendering/RenderLayer.cpp:
        (WebCore::RenderLayer::paintLayer):

        * rendering/RenderLayerBacking.cpp:
        (WebCore::RenderLayerBacking::contentOffsetInCompostingLayer):
        Remove a printf that I left in by mistake.
