One more issue arose with the semantics of LayerChromium:

in setNeedsDisplay( dirtyRect ), we are calling unite(dirtyRect).  This means that an empty dirty rect can cause the united dirty rect to be larger.

Is this important for some reason?  Can we change it to uniteIfNonZero(...) instead?

Once this and all the other questions are answered, I'll go ahead and submit another patch.

Thanks!
