CONSTify input strings where possible.

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.

Stick current alias on logslum slider -- there's room enough.

strips are picked.

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.

New pickrange.
Don't forget to redraw after "Backtrip".

(either before or after "kira" reader).

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

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

Use new "kira tree" cmd.

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.
