11 * (C) 1998,1999 by Marcin Dalecki <martin@dalecki.de>
13 * Support for GTK+ 2 was added by:
15 * (C) 2002,2003 Jason Hildebrand <jason@peaceworks.ca>
16 * Daniel Elstner <daniel.elstner@gmx.net>
18 * This is a special purpose container widget, which manages arbitrary
19 * children at arbitrary positions width arbitrary sizes. This finally puts
20 * an end on our resize problems with which we where struggling for such a
21 * long time.
