    wayland: Refine fullscreen/unfullscreen to emit the state change events
    
    Also update the code to set the size of the stage to set it to the size of the
    output. In future versions of the Wayland protocol we'll get a configure
    message advising of us of the size we can be to achieve fullscreen.
