* Revision History:
* 01-Nov-2000: Allocation checks
* 06-Jun-1997: Compatible with xscreensaver and now colorized (idea from
* xscreensaver but colors are random).
* 27-Feb-1996: Added new ModeInfo arg to init and callback hooks. Removed
* references to onepause, now uses MI_PAUSE(mi) interface.
* Ron Hitchens <ron@idiom.com>
* 10-Oct-1995: A better way of handling fortunes from a file, thanks to
* Jouk Jansen <joukj@hrem.stm.tudelft.nl>.
* 21-Sep-1995: font option added, debugged for multiscreens
* 12-Aug-1995: xlock version
* 1992: xscreensaver version, noseguy (Jamie Zawinski <jwz@jwz.org>)
* 1990: X11 version, xnlock (Dan Heller <argv@sun.com>)
