so results can be used as:
   perl tilesnap ... > something.cf
and then "read something.cf".

to generate images of resolution higher than the display can handle.

Add new SUBSTITUTE warp-type ("-subst field0"), which maps
three successive fields -> XYZ position (time-independent).

in each of the files that uses alloca.

camera's distance to a given (world-coordinate) focal point.

Add parti_focalpoint().

CONSTify getfloats().

Add "wait" option -- wait until end of "play".

It now returns void.
Fix (?) interaction between "winsize" and "detach".
At least, it works to say in .partiviewrc
    eval winsize 800x600+400+50
    eval detach hide
to get a bare graphics window with no UI panel.

for his implementation of Chromatek stereo, which color-encodes by
distance from the camera.

(chultquist@smuts.uct.ac.za, student of Anthony Fairall), as part of his
Computer Science Honours project.  Works with Chromatek glasses,
which make red things look nearby, blue things far away.
New commands:
   chromadepth {on|off}
	replaces colors of points and polygons with depth-coded colors
   chromaparams ZSTART ZRANGE
	sets Z-range (distance from camera plane) over which
	colormapping applies.  Z=ZSTART maps to first entry,
	Z=ZSTART+ZRANGE maps to last entry in colormap.
   chromacmap  FILE.CMAP
	Specifies colormap.
See example files data/chromadepth.cmap and data/hipchroma.

   "all"  - revert to autoranging
   "abs [base]"  - lum = scalefactor * abs(value - base)
   "lin"  - default behavior (unsets any "abs")

group-buttons while in motion, and new .pb file format.

binary particle format!

small additions/changes to make os x and windows buildable and functional. open issues on windows time motion widgets and terminating cleanly.
