/* $Header: /home/jcb/MahJong/newmj/RCS/lazyfixed.c,v 12.1 2020/05/30 17:27:18 jcb Exp $
* lazyfixed.c
* A slight variation on the GTK+ fixed widget.
* It doesn't call queue_resize when children removed;
* this can reduce flickering in widgets with many children.
* Of course, it means that you must call gtk_widget_queue_resize manually
* if you *do* want to remove something and have the size change.
* Also, of course, if you remove a non-window widget, nothing will
* happen until the next time something causes redisplay.
