Can repaintUsingContainer take a RenderElement& after this change?

Yeah, I've been considering that change for a while, but I don't think we are there yet. After https://bugs.webkit.org/attachment.cgi?id=459627&action=prettypatch, where both repaint and repaintRectangle start replacing null_ptr repaint container with the view(), I think it should be relatively easy to do.
