[gtk+/widget-expand: 3/3] add tests/testexpand.c used to test the expand props on GtkWidget

[Havoc Pennington <hp src gnome org>]

commit bdd4d59e2fe84de39985a8f53e7e421fa8dc292a
Author: Havoc Pennington <hp pobox com>
Date:   Mon Sep 6 12:31:54 2010 -0400

    add tests/testexpand.c used to test the expand props on GtkWidget
    
    There are two colored boxes with toggle buttons nested
    inside several GtkBox. Toggling these to expand mode
    should automatically propagate expansion up through
    the several GtkBox such that resizing the window
    results in resizing the colored boxes.
