Oops, now kira_draw needs to ensure we really have something to draw!

Update cookedcmap when "cment" changes cmap.

Toss unused variable.

``extern "C" { ... }'' doesn't need a post-semicolon.

OK, toss those extra 'break's.

Add "kira tree" support -- tree arcs, with crosswise tick-marks
at center-of-mass points.  Tickmarks lie in screen plane, with
length of <tickscale> times true separation.

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.

Add everycomp, depthsort fields.

Add rint() function.

Lots more caching (e.g. of texture slot numbers and texture id's) for speed.

txbind(NULL, NULL) invalidates currently-bound-texture-id cache.
Allow texture index 0 to hold a texture.  This allows for
kludges like using a [0..1) coordinate as a constant texture index.

Handle new texture attributes: alpha (-> 2-channel tx with luminance=0),
intensity (luminance=1, alpha=brightness).

Add parti_allobjs() for "gall" command.

Make it work under WIN32 (ugh); and allow CAVETime.
Allow null time ranges so partiview can suppress time bar
if nobody has nonempty range.

Add parti_allobjs() to implement "gall" command.

Don't show time-control bar unless some object has a nonzero
time range.

"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.

Use config.h's WORDS_BIGENDIAN.

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

Add "kira track" command for particle tracking.

Re-extract whenever kira_set changes something.
Add particle tracking.
Compute ring sizes correctly, and draw rounder rings.

Keyboard shortcuts "<" and ">" stop animation.
Shortcuts "{" and "}" start animation (backwards & forwards).

Add parti_nudge_camera() to aid in tracking objects.

Get slider position right if min/max values change.

Improve color choices, jog-roller resolution.

Fix some clock bugs.
Middle- or right-click on "step" buttons advance by .1 or 10 times normal step.
Tie step to speed: step = 0.1sec * speed.

Tidy up messages -- don't append \n in msg() calls.

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.

Add -lm to -lGL/-lMesaGL tests, to ensure it doesn't fail to find GL
just because libGL/libGLU use sqrt etc.!
Discard tests which search for IrisGL and PEX, since we can't use them anyway.
Re-install "depended"/"Makedepend" fix.  We really do want to force
Makedepend to be rebuilt, I think.

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

Lighten the text in timebase panel.

Rather than archiving an (incorrect) copy of Makedepend,
just have "configure" create an empty Makedepend and force
"make depend" to be invoked if the user then says "make".

We don't want to archive this file -- it's system-dependent!
Instead, "configure" does a "touch Makedepend",
and "Makefile" uses a "depended" tag-file to ensure that
"make depend" actually gets run once.

Handle wrap band correctly (no extra ";"!).

Add flag for "user limited time range", and wrap-band interval.
