I think windowLayer should be always in sync with NSWindowOpaque state. And 
both should be changed together via setOpaque() method.

The change above will call the "setWindowLayerOpaque" twice:
 - 
LWWindowPeer()->platformWindow.initialize()->contentView.setWindowLayerOpaque(true)
 - 
LWWindowPeer()->initializeImpl()->setOpaque()->contentView.setWindowLayerOpaque()
