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.

Let's see if it all works together.

MacOS X port, "home" command/button, lots of bug fixes -- into main branch!

Try to add pthread-based USE_IEEEIO.  Don't know if this works yet,
but it compiles.

Build up attrs incrementally.

Initialize 3 lights instead of 2.
Fix "partiview -c 'detach hide'".  It was being interpreted as "detach fullscreen"!

when copying a vvec<> or a WavObj.

under gcc 3.2 (not sure if 2.9x is broken...).

Any other settings we need to undo?
