Xmartin Revision History
------------------------
xmartin 2.2 (patchlevel 2) - 24 July 1991
-----------------------------------------
o new patterns: polar coordinate renderings of Pickover sine sculptures.
Plus 3 new functions: ejk4(sine-sqrt hybrid), ejk5(sine-linear hybrid),
ejk6(arc sine)
o -coord {xy|yx|ra|ar} coordinate mode (the last two are polar)
o parameter display changes
o changes for clean compile on RT 4.3 and other platforms
o xmartin+ accepts -f as equivalent to -n.
o general code & documentation cleanup
xmartin 2.1 (patchlevel 1) - 16 June 1991
-----------------------------------------
o new pattern function (-f ejk3)
o static (XImage) plotting mode is back by popular request (-static)
o Sequent/Convex color parsing fix
o default dynamic points lowered from 8192 to 1024 to prevent X-Vision
& XSight server crashes
o xmartin+ recognizes xmartin "-d" option
xmartin 2.0 (patchlevel 0) - 8 June 1991
----------------------------------------
o new patterns: Clifford Pickover's 1st->16th order sine sculptures from
the January 91 Algorithm. And a generalized exponent version of the
Martin square root by Renaldo Recuerdo of the Santa Cruz Operation.
o option/resources for subdued color background (including random)
o special grayscale display resources & defaults
o black-on-white +rv option
o support for DEC window manager & for multi-screen displays
o new xmartin+ options: -repeat, -save
o -p/-P values of 100 or less interpreted as % of display/tile pixels
o random number improvements: seed period increased from 12.1 days to 17
years; initial numbers in sequence skipped to prevent similar seeds on
consecutive executions.
o XImage ("static") plotting mode removed to simplify background color
options & the X interface in general. Measurements indicated XImage
mode improved elapsed time substantially only in the case of full screen
(non-tiled) patterns on very fast clients to remote monochrome servers,
and then only by ~15 seconds. If "-dynam" is omitted, plotting now
defaults to "-dynam 8192".
xmartin 1.1 (patchlevel 1) - 25 April 1991
------------------------------------------
o tvtwm (Tom's Virtual Tab Window Manager) support
o fix test for color display in xmartin.c hopalong()
o minor code & documentation cleanup
xmartin 1.0 (patchlevel 0) - 8 April 1991
-----------------------------------------
o new patterns with three variations on the original Martin hopalong
o option for tiling effects and/or speed
o option for effects by periodically perturbing (x,y)
o random color sequences and tailorable resources for colors
o ranges for hopalong parameters
o zoom and pan options
o option to recall and alter previous hopalong parameters
o optional Perl xmartin+ tailors probabilities, replays interesting patterns
xfroot - 4 June 1990
--------------------
o color and dynamic (display-as-calculated) options
o new algorithm for random default parameters
xfroot - September 1989
-----------------------
o original monochrome version
