 * Example originally written by Bruno Tatibouet <[e-mail]>,
 * (thanks Bruno !) expanded later to show more cases (XtSetValues on several
 * resources of the input and output objects).
 * The original example only showed that resources at creation time didn't
 * have effect on the input and output objects.
