 *
 *
 *      Changes:
 *
 *      Version 1.25  - released July 2, 1999.
 *                      Some optimization + ignores double click if no command set (patch from
 *                      Robert Horn).
 *
 *      Version 1.24  - released March 27, 1999.
 *                      Added support for additional fonts for time field;
 *
 *                              -tekton for Tekton
 *                              -arial  for Arial (Helvetica) (this is the same font as usual)
 *                              -luggerbug for LuggerBug
 *                              -comicsans for ComicSans
 *                              -jazz for JazzPoster
 *
 *                      Different width fonts get used depending on whether or not seconds
 *                      are displayed.
 *
 *      Version 1.23  - released March 20, 1999.
 *                      Switched from wmgeneral.c stuff to xutils.c (a more stripped down version
 *                      of wmgeneral).
 *                      Centered Calendar text better.
 *                      Added command line options and code to change colors of the time
 *                      field digits and the background of the time field. So now you can
 *                      get things like darkblue on light grey or very dark color on an LCD-ish
 *                      colored background (e.g. wmCalClock -bc #6e9e69 -tc #001100)..
 *                      Rewrote the command line parsing routine.
 *
 *      Version 1.21  - released February 4, 1999.
 *                      cosmetic for AfterStep users. removed spurious black line at RHS edge of mask.
 *
 *      Version 1.20  - released January 14, 1999.
 *                      Changed support for LowColor Pixmap. Now, check for Depth
 *                      automatically. If its <= 8, then use LowColor.
 *
 *
 *      Version 1.11  - released January 8, 1999.
 *                      Fixed bug in 12-hour mode. Now displays 12:xx:xx AM instead
 *                      of 0:xx:xx AM.
 *
 *
 *      Version 1.10  - released January 7, 1999.
 *                      Added support for LowColor Pixmap. (21 colors may still be a
 *                      bit high, but the poor saps with 8-bit displays can at least run
 *                      it now.)
 *
 *      Version 1.02  - released January 7, 1999.
 *                      Fixed bug in AM/PM determination...
 *
 *      Version 1.01  - released January 3, 1999.
 *                      Added "-S" option to inhibit drawing of seconds.
 *
 *      Version 1.00  - released December 16, 1998.
