    embed: Set up a better initial state
    
    The GtkClutterEmbed widget should turn on the APP_PAINTABLE flag, since
    it's responsible for painting everything, including the background.
    
    It should also set the h-expand and v-expand properties to TRUE, as the
    container of the widget should allocate all the extra space; this allows
    us to get rid of the explicit set_size_request() in a bunch of places.
