Actually, it occurs to me that Kip is almost certainly going to want
to change the size request methods to:
     def do_get_preferred_width(self):
        pw = self.pb.get_width()
        return (0, pw)

    def do_get_preferred_height(self):
        ph = self.pb.get_height()
        return (0, ph)

    def do_get_preferred_height_for_width(self, width):
        ph = width / self.get_aspect_ratio()
        return (ph, ph)

Otherwise it won't scale down properly.
