    window-x11: The x11 backend window is our window as well
    
    Since commit 467465c99c41 we use meta_stage even on x11 which sets
    clutter_stage_set_user_resizable to FALSE.
    
    This messes things up because we ought to ignore the properties on the window
    but we apperently didn't.
    
    There is no reason why we'd want to manage the stage window.
