        * gtk/gtkcontainer.c (gtk_container_set_resize_mode): fail silently
        for toplevels. if resize_mode changes to GTK_RESIZE_PARENT, clear the
        resize widget list before queuing the container for a new reize.
        (gtk_container_need_resize): changed return value to FALSE, since this
        used to indicate that no further resizes are needed.
        (gtk_container_set_arg):
        (gtk_container_get_arg):
        (gtk_container_class_init): implemented GtkContainer::resize_mode
        argument.

        (gtk_container_resize_children): when we walk up the tree of a resize
        widget we need to stop if we are the current parent.

        * gtk/gtkwidget.c (gtk_widget_queue_resize): flag the resize child with
        GTK_RESIZE_NEEDED for container->resize_mode==GTK_RESIZE_IMMEDIATE.
        (gtk_widget_hide_all): retrive the toplevel widget from via
        gtk_widget_get_resize_container().
