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")

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

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.

we choose the orientation of the master pipe.

Add Illinois-open-source-license reference to LICENSE.partiview file.

instead of object coordinates.

Once we pick a license this might change, but
in the mean time, at least the NCSA UIUC origin is noted.

otherwise just x y z rx ry rz scale; print matrices in %g format for
full precision; accept 7th parameter as scale factor on input
just as we print it on output.

and refer specifically to Marcus Thiebaux's virdir
since there's now also a Matt Hall version.

now moved into partimenu.c.

"rawdata -a" particle-dump includes position, color, brightness too.

Default change: no longer skip blank times!
Per-data time ranges now extend overall clock range,
don't replace it.
Reset material properties (shininess, specular, ambient)
when drawing a lighted mesh.

"where" command gives full-precision values, and reports jump-pos with scale.
Allow for model-specific render function (initially for Maya models).
env TXDEBUG.

a single timestep ourselves!

Add pointsize metering, normally #ifdef USE_PTRACK'ed out.

Fix tokenize() for case of "quoted" or 'quoted' arg strings.
