Carlos R. Mafra 21625f40b5 Initial dockapps git repo 
I tried to get the latest versions from dockapps.org, but I haven't
tested any of them.

More dockapps will be added as time permits.

*
*
* 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.
*
