I think James has brought up a good point, though, in his reviews, which is essentially that our current use of the LayerChromium is extremely hacky. The reason for this is because root vs non-root layers behave differently in WebKit.

What I have done in the new patch is to stop the root layer damage logic from piggybacking on the LayerChromium code. By pulling it into the WebView, we keep our code clear.

My guess is that iframe handling will end up driving us to resolve root vs non-root issues. A bug for this exists at http://code.google.com/p/chromium/issues/detail?id=54758. I think that bug will ensure that the root-non-root concerns brought up in this discussion will not get swept under the rug.
