+/*  Gtk+ User Interface Builder
+ *  Copyright (C) 1998  Damon Chaplin
+ *
+ *  Update 3/17/99 - Jay Johnston:
+ *  - added property adjustments
+ *    - style
+ *    - orientation
+ *    - activity mode
+ *    - show text
+ *  - added sample animation (most of that code was taken from the Gtk v1.2
+ *      tutorial by Tony Gale <gale@gtk.org> and Ian Main <imain@gtk.org> )
+ *  - added dynamic popup menus which change depending on whether the animation
+ *      is active or not
