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.

emphasis tag.
Use new sfStrDrawTJ (with transform & justification) for text.
Yeow, handle polymax properly -- default == infinity!
Add "vcmap" for per-datafield colormaps.
Enable GL_SMOOTH mode to get texture colors to work right (huh? why do we need to?).
"tfm c"/"tfm w" choose cam vs. world (default) location for object tfms.

popen() needs "r" not "rb" -- no such thing as binary mode.
kira_open() gets original filename if we can't find it, for error messaging.

Now, the only #ifdef KIRA/WARP needed in partibrains.c are
the data-command initialization routines.  All others,
including control-command parsing and specialized drawing,
is now via a function table.

Put colorseq/sizeseq/threshseq invalidation in kira_parti, not here,
since we needn't do it when warping.
By default, clock range is whatever it had been set to before.

Initialize all dynamic-data stuff explicitly.

Ellipsoids allow 3-component (Rx Ry Rz) orientation numbers too.
st->dyndata doesn't mean we should trash the anima[][] specklist.
Need to keep it intact for warping.

Finally parse snapshot arguments properly...?

snapshot/snapset.  Not actually implemented yet.
Add "clipbox hide".  This (a) doesn't display the big yellow box
and (b) doesn't enable OpenGL clipping -- just whatever object culling
the draw routine does anyway.
specks_draw_mesh() now pays attention to drawing style (solid/line/plane/point).
When drawing ellipsoids, disable blending altogether if bgcolor != 0.
Small, distant labels now disappear by default.  To get the old
draw-tiny-line behavior, use a negative "labelmin" value.

Add "ghosts" ctl command (not really implemented).
Add "winsize" ctl command.
Ellipsoids now accept -l levelno option, in which case
"hide levelno"/"show levelno" applies to them.  Default is -1,
which means "show if any level is shown", but hidden by "hide all".
Scrap ghost maintenance.  Do that elsewhere instead.
Make "maxcomment" work properly.

New "version" command in partibrains reports that and the partibrains.c CVS ver no.

Have a separate "comment" pointer.  Pass it to specks_read_ellipsoid too.

Complain of unrecognized data commands.

"object" command alone reports our currently selected object.
