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.

and out of this overstuffed piece of junk.

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.

don't overwrite args in memory.

inside #ifdef brackets.

all those maintained by specks_timespecksptr.  We no longer guarantee
that st->curtime is always in range 0..st->ntimes-1, so just yield NULL
for out-of-range references.  New CURDATATIME(fieldname) does it.

Only call parti_parse_args() if non-CAVE.

and into partiview.cc, using new parti_add_commands hook.

"where" prints more information.

Fix seldest2src(), not even wrong.
Use specks_reupdate() after changing thresh, so the reported
selcount should be right.
specks_rethresh(): keep track of whether anything changed,
and increment st->selseq if so.

both were filled in.

Revert to compatible texture behavior: texture -A is again the default,
use texture -O for "over"-style blending.

``sel <src>'' alone now works too, to just report match count.

And, report match counts from "sel", "thresh", "emph".

    selsrc(), seldest(), selname(), seltoken().
"thresh" now accepts "-s 'destexpr'".
Add new selthresh SelOp.

Next: implement "see" in drawspecks().
Add "picked" callback which gets notified of all pick results.
