    window-actor: Kill off a nonsensical edge case
    
    We can never have a window actor that represents either the X root
    window or the stage window, so it doesn't make sense to bail out
    early in case we do.
    
    I'd imagine that this came from a much earlier version of the code
    where the compositor was much separate and had its own MapNotify
    handling.
