Summary RenderLayer cached clip rects are sometimes incorrect

I added an assertion to test that cached clip rects are used with the same rootLayer as they were computed with. This caught a couple of problems, which I'll submit a patch for.

Created attachment 26241 [details] Patch, changelog I wasn't able to easily create a LayoutTest to exercise these fixes, but the assertion provides testing.

Also, did you know that clipRects are cleared on every mouse move, because MouseRelatedEvent::receivedTarget() calls layer->updateLayerPosition() before setting event->layerX and event->layerY (which are totally bogus anyway, bug 21868).
