/**
 * This program demostrates two bugs in LessTif's XmScale widget:
 *
 *   (1) Setting XmNwidth doesn't have any effect.  (However,
 *         XmscaleWidth works)
 *
 *   (2) The first time the window is drawn the first label gadget is missing.
 *                       (However, it shows up after a refresh.)
