Rename FrameView's repaintRectangle method to repaintContentRectangle.  Make
        both it and ScrollView's updateContents method be off-limits to everyone in
        WebCore except for RenderView.

        Make repaintViewRectangle the only possible method for WebCore code to do
        an invalidation.  This ensures that all invalidates triggered by WebCore
        cross-platform code that cross ownerElement() boundaries are transform-aware.

        Make sure that iframes/frames contained inside objects that have transforms
        or reflections are not allowed to blit (this was already true for transparency).

        It is not possible to make a test for any of this, since iframe scrolling
        still doesn't work on Mac (since the invalidates are not being done
        through WebCore's cross-platform invalidation code but are instead going
        through NSScrollView's setNeedsDisplay still).
