Try to coalesce some composited layers. If subtree compositing flag is off, and the layer is fully inside the ancestor, there is no need to do the overlap test. This will reduce a lot of sub layers. --klobag

I think this might be a duplicate of what smfr is trying to do in https://bugs.webkit.org/show_bug.cgi?id=50192. smfr: What's the status on that patch?
