Declare getfloats() (from partibrains.c at the moment).

"where" prints more information.

(Some "kira" commands use kira_set(), which already does this.
Just set "changed" for those which don't.)
Impose a max trail gap (delta time).  Break up trails at time-gaps
exceeding this threshold.

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.

the kira-computed smoothed cluster center.

New "kira hrdiag" command allows turning it on/off, setting plot ranges.
"kira int x" is a synonym for "kira int x=x", the common case.
New "sqrtmass" attribute.  "mass" is again in linear, not log units.
Disable kira display if we don't get a valid input file.
XXX Bogusly import getfloats() from partibrains.c; should go in a separate
utility .c/.h file.

both were filled in.

of picked stars.

dynamical->solar mass unit conversion.
If it knows, then "kira massscale" only allows user
to override if user-supplied value ends with "!",
e.g. "kira mscale 600!".

Revert to compatible texture behavior: texture -A is again the default,
use texture -O for "over"-style blending.

from previous time.  Add TXF_OVER txflags bit.

``sel <src>'' alone now works too, to just report match count.

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

of command/history box.  Needs to be set before they're created,
apparently -- ctrl-K trick doesn't work so well.

Doesn't seem to work, though -- I still see the regular old arrow.  Why not?

able to track collections rather than single particles (not yet though).
Trails are relative to tracked-point position, so can be non-inertial.

Warp pointer under X.
And, justify numeric labels so they're always visible.
