*
* Revision History:
* 01-Mar-2003: Added shooters for triangular life.
* 26-Feb-2003: Added LWSS, MWSS, HWSS in shooter.
* 25-Feb-2003: Randomly rotate trilife
* 25-Jan-2003: Spawned a life.h
* 23-Jan-2003: Added life from Stephen Silver's Life Lexicon
* http://www.argentum.freeserve.co.uk/lex_home.htm
* 23-Jan-2003: Tri life from Carter Bays. Added B45/S34 which I use as
* the true trilife, also available B456/S45 & B45/S23.
* Right now the glider for trilife is not integrated into
* the "shooter" part of the program.
* Other neat ones are B4/S456, B46/S24, B4/S35, B456/S12,
* B3/S23, & B4/S46. See:
* http://www.cse.sc.edu/~bays/trilife3/home.html
* 15-Jan-2003: Moves on if screen blank or static
* 15-Jan-2003: Alternate life rules from Nathan Thompson's "Day and Night"
* B3678/S34678 and David I. Bell's "HighLife" B36/S23.
* See http://www.tip.net.au/~dbell/
* Other rules that may be neat:
* http://entropymine.com/jason/life/alt/
* "Diamoeba" B35678/S5678, "Move" B36(8)/S245
* 01-Nov-2000: Allocation checks
* 03-Oct-2000: Added more randomness in pattern 90 degree orientation and
* mirror image.
* 08-Dec-1997: Paul Callahan's B2a/S2b34 rule added.
* Described on the news site for cellular-automata.
* <ppc997@aber.ac.uk>
* http://www.cs.jhu.edu/~callahan/lifepage.html
* http://www.cs.jhu.edu/~callahan/hexrule.txt
* B2a/S2b34: Birth of x if 2a,
* Survival of x if 2b, 3, or 4 neighbors
* Assume symmetry.
* (2a, 2b, 2c: 2o, 2m, 2p original notation)
* O O O . O .
* 2a: . x . 2b: . x O 2c: . x .
* . . . . . O
* Also Bob Andreen's rule (my own notation for consistency)
* B2a3a4b/S2a2b4a (original notation: 234'B/22'4S)
* <andreen@msmc.edu>
* O O O O O .
* 3a: . x O 3b: . x . 3c: . x O
* . . . O O .
*
* O O O O O O
* 4a: . x O 4b: . x O 4c: . x .
* . O O . O O
* Some other rules
* B2a3b3c5/S12b2c3a4b4c6
* B23a3c4b4c6/S12b2c3c4a56
* B2a2c6/S13b
* 27-Oct-1997: xpm and ras capability added.
* 04-Jun-1997: Removed old algorithm, now use wator's. I could not
* understand it and had trouble adding more features.
* New algorithm is more efficient iff there lots of blank
* areas (ptr loop rather than a double array loop)
* 10-May-1997: Compatible with xscreensaver
* 07-May-1997: life neighbor option. Still have to fix -neighbor 3
* 07-Jan-1995: life now has a random soup pattern.
* 07-Dec-1994: life now has new organisms. They are now better centered.
* Some of the nonperiodic forms were removed. New life
* forms were taken from xlife (an AMAZING collection of life
* forms). life's gliders now come from the edge of the screen
* except when generated by a life form.
* 23-Nov-1994: Bug fix for different iconified window sizes
* 21-Jul-1994: Took out bzero & bcopy since memset & memcpy is more portable
* 10-Jun-1994: Changed name of function 'kill', which is a libc function on
* many systems from Victor Langeveld <vic@mbfys.kun.nl>
* Changes in original xlock
* 24-May-1991: Added wraparound code from johnson@bugs.comm.mot.com.
* Made old cells stay blue.
* Made batchcount control the number of generations until restart.
* 29-Jul-1990: support for multiple screens.
* 07-Feb-1990: remove bogus semi-colon after #include line.
* 15-Dec-1989: Fix for proper skipping of {White,Black}Pixel() in colors.
* 08-Oct-1989: Moved seconds() to an extern.
* 20-Sep-1989: Written, life algorithm courtesy of Jim Graham <flar@sun.com>
