It's easy to crash on IE Flying Images if you increase the number of images a bit. Tiled backing layers shouldn't have backing store themselves! But they do, because of a silly mistake in http://trac.webkit.org/changeset/158417... we can't dirty the whole layer if we have no existing front buffer if we have no paints, because that will lead to layers which were never setNeedsDisplay()'d getting backing store. Added back an assertion that will catch this, too. Probably we should strengthen the mechanism that causes never-setNeedsDisplay'd layers from getting backing store.
