A bit of code in this function is confusing me:

  if (requisition.width > widget->allocation.width ||
      requisition.height > widget->allocation.height)
      if (GTK_IS_RESIZE_CONTAINER (container))
        gtk_widget_size_allocate (GTK_WIDGET (container),
                                  &GTK_WIDGET (container)->allocation);
        gtk_widget_queue_resize (widget);

I'm trying to understand the logic behind the GTK_IS_RESIZE_CONTAINER case. If 
it is known that the requisition is greater than the allocation, why is the 
widget allocated with insufficient space? Are container implementations supposed
 to do something special to handle this case?
