*
* Revision History:
*
* Changes maintained by David Bagley <bagleyd@tux.org>
* 23-Feb-03: Timothy Reed <treed1@twcny.rr.com>
* Added PAM_putText to converse with passwd.c PAM_conv function
* to converse with any PAM.
* 09-Mar-01: showfps stuff corrected
* 01-Nov-00: Allocation checks
* 08-Apr-98: A way for users to unlock each others display. Kind of defeats
* the lock but the unlocked user is mailed and and entry is
* written to syslogd. Thanks to Mark Kirk <mkirk@pdi.com> for
* his vizlock-1.0 patch. Compile-time switch for this is
* GLOBAL_UNLOCK. This is probably full of security holes when
* enabled... :)
* 01-Jul-98: Eric Lassauge <lassauge AT users.sourceforge.net> &
* Remi Cohen-Scali <remi.cohenscali@pobox.com>
* Added support for locking VT switching (-/+vtlock)
* Added code is enclosed in USE_VTLOCK
* 01-May-97: Matthew Rench <mdrench@mtu.edu>
* Added DPMS options.
* 02-Dec-97: Strong user authentication, utilizing the SafeWord API.
* Author unknown.
* 01-May-97: Scott Carter <scarter@sdsc.edu>
* Added code to stat .xlocktext, .plan, and .signature files
* before reading the message; only regular files are read (no
* pipes or special files).
* Added code to replace tabs with 8 spaces in the plantext buffer.
* 01-Sep-96: Ron Hitchens <ron@idiom.com>
* Updated xlock so it would refresh more reliably and
* handle window resizing.
* 18-Mar-96: Ron Hitchens <ron@idiom.com>
* Implemented new ModeInfo hook calling scheme.
* Created mode_info() to gather and pass info to hooks.
* Watch for and use MI_PAUSE value if mode hook sets it.
* Catch SIGSEGV, SIGBUS and SIGFPE signals. Other should
* be caught. Eliminate some globals.
* 23-Dec-95: Ron Hitchens <ron@idiom.com>
* Rewrote event loop so as not to use signals.
* 01-Sep-95: initPasswd function, more stuff removed to passwd.c
* 24-Jun-95: Cut out passwd stuff to passwd.c-> getPasswd & checkPasswd
* 17-Jun-95: Added xlockrc password compile time option.
* 12-May-95: Added defines for SunOS's Adjunct password file from
* Dale A. Harris <rodmur@ecst.csuchico.edu>
* 21-Feb-95: MANY patches from Heath A. Kehoe <hakehoe@icaen.uiowa.edu>.
* 24-Jan-95: time_displayed fixed from Chris Ross <cross@va.pubnix.com>.
* 18-Jan-95: Ultrix systems (at least DECstations) running enhanced
* security from Chris Fuhrman <cfuhrman@vt.edu> and friend.
* 26-Oct-94: In order to use extra-long passwords with the Linux changed
* PASSLENGTH to 64 <slouken@virtbrew.water.ca.gov>
* 11-Jul-94: added -inwindow option from Greg Bowering
* <greg@cs.adelaide.edu.au>
* 22-Jun-94: Modified for VMS
* <Anthony.D.Clarke@Support.Hatfield.Raytheon.bae.eurokom.ie>
* 10-Jun-94: patch for BSD from Victor Langeveld <vic@mbfys.kun.nl>
* 02-May-94: patched to work on Linux from Darren Senn's
* <sinster@scintilla.capitola.ca.us> xlock for Linux.
* Took out "bounce" since it was too buggy (maybe I will put
* it back later).
* 21-Mar-94: patch to to trap Shift-Ctrl-Reset courtesy of Jamie Zawinski
* <jwz@jwz.org>, patched the patch (my mistake) for AIXV3
* and HP from <R.K.Lloyd@csc.liv.ac.uk>.
* 01-Dec-93: added patch for AIXV3 from Tom McConnell
* <tmcconne@sedona.intel.com> also added a patch for HP-UX 8.0.
* 29-Jul-93: "hyper", "helix", "rock", and "blot" (also tips on "maze") I
* got courtesy of Jamie Zawinski <jwz@jwz.org>;
* at the time I could not get his stuff to work for the hpux 8.0,
* so I scrapped it but threw his stuff in xlock.
* "maze" and "sphere" I got courtesy of Sun Microsystems.
* "spline" I got courtesy of Jef Poskanzer <jef@netcom.com or
* jef@well.sf.ca.us>.
