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.

reports object name before invoking each command.

Data-language references can create, command-language ones can't.
Switch specks_read() to argc/argv style, using new "tokenize()" function.
Some commands still want the original string, so we also have rejoinargs().
Allow for adjustable comment length with "maxcomment" data command.
New "ellipsoid" and "mesh" objects.  Only quadmeshes implemented right now.
Data-language "tfm" command is now quiet.  Command-language tfm still verbose.
Check at run time for endian-config errors and refuse to run if wrong!

Allow alpha to adjust brightness of mesh objects.

polyorivar and texturevar now accept field names as well as numbers.

alias or not!

Then "txscale .5" always shows entire texture regardless of polysides.
Add new "ptsize" command -- makes more sense than "fast".  "fast" still works.

Then, for "polysides 4" and "txscale .707",
the vertices coincide with the corners of the 0..1 texture.

Object aliases: "object gN=ALIAS", or in command mode, "gN=ALIAS".
Accept "ellipsoid" data tag; not yet implemented.

Add "pickrange".
Mention jump, center in help msg.

Don't let "kira tree" hide "kira track" -- demand 3 chars!

Update cookedcmap when "cment" changes cmap.

Toss unused variable.

Add "setgamma" (abbr. "setgam" or "cgam") command to adjust colors.
Add "kira tree {off|on|cross|tick} [tickscale]" subcommand
for showing tree structure of interacting groups.

Ensure that, for starlab, clock is always in "continuous" mode.

Add RCS Id and Log strings.

"depthsort" adds depth-sorted polygons.
New texture qualifiers -i(ntensity) -a(lpha) -A(dd).
New "gall" (a.k.a. "allobj") cmd sends following command to all objects.
"everycomp" says whether to compensate for "every" subsampling.

Add new "trange" command to specify a limited range of times we're
allowed to view.

Add "kira track" command for particle tracking.

Add ring markers for non-isolated stars.  Not finished yet, but seems usable.
No GUI yet, but new commands:
   kiractl nodes  {on|off|roots}
   kiractl rings  {on|off|roots}
   kiractl ringsize {sep|semi}   (ring size from curr. separation or semimajor axis)
   kiractl scale  <scalefactor>
   kiractl span   <minpixels> <maxpixels>   (allowed range of ring radii)

Change encoding of nclump: n for leaves, -n for center-of-mass nodes,
   so colormap can make them distinguishable.

Bug: after kiractl command, must change timestep before it takes effect.
Bug: ring markers aren't colored yet for some reason.

Reduce SPECKCHUNK to 2001, not 10001.  Too many machines have tiny stacks.

User-adjustable wraparound time (but no way to adjust it yet).
Recompute colors and sizes whenever we update dynamic data.
Don't update dynamic data if time hasn't changed.
Discard old specks when updating dynamic data -- but allow for
keeping "ghost" copies (up to st->nghosts) for making trails.
We don't do trails yet though.

Lots of changes to support new time flow and additional
time-related GUI.  Probably not all there but at least somewhat usable.

Don't report error if WORDS_BIGENDIAN is undefined -- config.h might
just /* #undef */ it.  Just assume undefined -> false.

We're little-endian if WORDS_BIGENDIAN is defined (in config.h) and set to 0,
so use #if rather than #ifdef to test endian-ness.
