Here's why I thought it would be better to override opaque() instead:  If we set the bit for a NonComposited surface, we will have have to put checks in the code in every other place that unsets the bit to check if it's NonComposited.  And that makes more special case code than we have now. Am I wrong about this?

If not, we could check isNonComposited() rather than !m_parent in opaque().

I had thought you meant to remove the NonCompositedLayer entirely when you talked about removing special cases, but I guess that wasn't your intent.
