opacity is used heavily in OS X, both in Dashboard widgets and in apps  
that use WebKit.  It has been deployed for years.   Even if we could  
change it, I don't think we should, since I think having opacity  
follow the document tree is much more natural than having it follow  
the containing block hierarchy.
