Scott, could you have a look at this? I've changed phantom window controller to
use layers following your suggestion.

This seems weird. Can you talk with Antoine about this restriction.

Done. Talked with him and added set_delegate call to
WorkspaceWindowResizer::RecreateWindowLayers().

Now the WindowPainter class is gone.
