*
* See xlock.c for copying information.
*
* Revision History:
* Nov-04: updates by Eric Lassauge <lassauge AT users.sourceforge.net>
* - Version 3.0 : give a first try at GTK 2.x !
* Nov-99: updates by Eric Lassauge <lassauge AT users.sourceforge.net>
* - Callbacks for 'Cancel' buttons , don't SIGSEGV anymore
* - FontSelection dialog updates for GTK 1.2.6
* - Drawing of little colored rectangle simplified, now works in
* Pseudo 8 bits and doesn't need an 'expose'
* - Add 'About' box
* - Add handling of "similar to xmlock" RC file
* - etc...
* Jul-98: Continual improvements by Remi Cohen-Scali <remi.cohenscali AT pobox.com>
* ?? -98: First written by Charles Vidal <cvidal AT ivsweb.com>.

/*-
XgLock Problems are almost the same as XmLock's ones.
1. Allowing only one in -inroot. Need a way to kill it. (a menu ?)
2. Still missing many options (TO DO).
3. Need a clean rewritting.
