    wayland: Send a correct width / height for state changes
    
    If we send out a configure notify for a window and then have some
    other kind of state change, we need to make sure that we continue
    to send out that new size, rather than the last size the client
    sent us a buffer for.
    
    In particular, a client might give us a 250x250 buffer and then
    immediately request fullscreen. We send out a configure for the
    monitor size and a state that tells it it's full-screen, but then
    it takes focus, and since the client hasn't sent us a buffer for
    the new size, we tell it it's fullscreen at 250x250.
    
    Fix this.
