Thu Jan 23 20:56:56 GMT 2003  Tony Gale <gale@gtk.org>
        * Sebastian Rittau  <srittau@jroger.in-berlin.de>:

           docs/tutorial/gtk-tut.sgml: Adopted chapter 21.3 "Creating a
           Composite widget" to modern standards. (I.e. use gobject instead of
           glib, derive from GtkTable instead of GtkVBox.) Bugzilla #103869.

        * docs/tutorial/gtk-tut.sgml, examples/tictactoe: Fixup tic-tac-toe
        code in Appendix C to reflect above changes.

        * examples/rangewidgets/rangewidgets.c: From Roger Leigh
        auto resize on page size change
