/* Class for displaying messages, similar to wxMessageDialog,
 * but can be erased after a time out expires.
 *
 * @note - Do not use the time feature.  It is broken by design because
 *         the dialog is shown as modal and wxWidgets will assert when
 *         compiled in the debug mode.  This is because the dialog steals
 *         the event queue when dialog is modal so the timer event never
 *         gets to the dialog event handle.  Using dialogs to display
 *         transient is brain dead anyway.  Use the message panel or some
 *         other method.
