Add data for representing traj files (not yet used either).
Add data for drawing vectors at each point (this one is implemented now).

Add possibly-misguided ThReader structure.

Add "ready" parameter to dyndata trange method.

Add (not yet used) fcolors field to struct mesh.

Add parti_focalpoint().

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.

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

the validity test.

Where appropriate, update references to geomview license too,
now called COPYING.geomview.

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

31 (or maybe 32).

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.

Add "selcounts()" function to count particles matching given SelOp pattern.

Offer selsrc2dest(), seldest2src().

Add set-selection features: SelOp bitmasks, etc.

Add emphasis controls.

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.

Add seed counter to struct stuff.
