    embed: queue a draw on actors when embed state flag change
    
    When we receive a state-flags-changed signal, we should queue a draw on
    all of our children, since their appearance might be depending on
    inherited style values that changed.
    
    This should really be done generically by GTK, but doing it there is
    very bad for performance with the current GTK code, so we do it here.
