 * $Log$
 * Revision 1.42  2002/01/27 00:37:48  slevy
 * No need to bogusly import getfloats() any more.
 *
 * Revision 1.41  2001/12/28 07:18:36  slevy
 * Convert to new plugin style.
 *
 * Revision 1.40  2001/08/29 20:58:14  slevy
 * Try (?) to handle selection (leafsel/bufsl->sel) properly -- it seems
 * to interact with double-buffering.
 * Use preload_pdyn() to precompute trees for each worldbundle.
 *
 * Revision 1.39  2001/08/28 18:42:07  slevy
 * Yeow, refer to the proper ww->bufleafsel[]!
 *
 * Revision 1.38  2001/08/28 18:28:18  slevy
 * Switch (I hope) to double-buffered graphics data, flagged by ww->bufno.
 *
 * Revision 1.37  2001/08/26 17:36:46  slevy
 * Parenthesize ambiguous expressions...
 *
 * Revision 1.36  2001/08/26 02:11:07  slevy
 * Oops, toss extra glBegin(GL_POINTS).
 *
 * Revision 1.35  2001/08/21 03:11:05  slevy
 * Use Steve's new family of center-points -- "kira center" command.
 * Add new per-particle field, "ismember", to show escapees.
 *
 * Revision 1.34  2001/07/19 20:12:47  slevy
 * Reprocess particles after changing parameters.
 * (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.
 *
 * Revision 1.33  2001/07/18 22:41:45  slevy
 * Add "kira center" command, to report all positions relative to
 * the kira-computed smoothed cluster center.
 *
 * Revision 1.32  2001/07/18 19:45:34  slevy
 * Picked stars now report their type and spectral/luminosity classes too.
 * 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.
 *
 * Revision 1.31 2001/07/17 22:19:37  slevy
 * Use type_string(stellar_type) to get readable names for stellar types
 * of picked stars.
 * 
 * Revision 1.30 2001/07/17 17:29:36  slevy
 * Use new mass_scale_factor() to get starlab's idea of
 * 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!".
 * 
 * Revision 1.29 2001/07/16 19:08:30  slevy
 * #if(def)'s for CAVE, where we have no plot widget.
 * 
 * Revision 1.28 2001/07/16 17:55:55  slevy
 * Report log10(mass*massscale) -- log is handier than linear units.
 * 
 * Revision 1.27 2001/07/12 21:37:02  slevy
 * Lots of changes.  Add trails.  Move tracking code so we'll be
 * able to track collections rather than single particles (not yet though).
 * Trails are relative to tracked-point position, so can be non-inertial.
 * 
 * Revision 1.26 2001/07/10 17:15:50  slevy
 * Add massscale (mscale) for convenient mass presentation.
 * Compute fake aggregate temp/luminosity for CM nodes.
 * Oops, marks need their own sel[] array!
 * Allow adjusting H-R diagram alpha values too.
 * 
 * Revision 1.25 2001/07/09 19:57:22  slevy
 * Add H-R diagram zoom (b/B keys).
 * Pay attention to emph/see settings.
 * Get selection working properly.
 * 
 * Revision 1.24 2001/07/07 15:27:57  slevy
 * Save/restore positions of subparticles, so we can reuse interpolated_tree safely.
 * Only use SEL_DEST-initialized pick etc. info.
 * 
 * Revision 1.23 2001/07/04 03:28:03  slevy
 * Add picking support: kira_picked() gets all pick callbacks.
 * Add set-selection features, including interaction tracing.
 * 
 * Revision 1.22 2001/07/02 16:17:24  slevy
 * Cast kira_HRplot to avoid complaints.
 * Hack for gcc 3.0's stdio (#ifdef NEWSTDIO).
 * 
 * Revision 1.21 2001/07/01 14:30:43  slevy
 * Do more plot setup here in kira_parti.  Set axis titles too.
 * 
 * Revision 1.20 2001/07/01 07:31:45  slevy
 * Hmm, make default logT range a bit smaller.
 * 
 * Revision 1.19 2001/07/01 06:42:01  slevy
 * Oops, get the sense of the log-T scale correct!
 * 
 * Revision 1.18 2001/06/30 18:09:15  slevy
 * Add kira_HRplot for drawing in H-R diagram.
 * 
 * Revision 1.17 2001/06/30 07:01:47  slevy
 * Yes, call create_interpolated_tree2() if not OLDTREE!
 * 
 * Revision 1.16 2001/06/06 17:22:55  slevy
 * get_stellar_type() now returns int (enum from starlab/inc/star_support.h),
 * rather than a string.
 * 
 * Revision 1.15 2001/05/30 14:31:16  slevy
 * Add Tlog, Lum, and stellar-type fields.
 * Star type is number-encoded, sigh:
 * 	0 = unknown
 * 	1 = ms	Main Sequence
 * 	2 = cd	Compact Dwarf??
 * 	3 = gs	??
 * 	4 = bh	Black Hole
 * 	5 = sg	Supergiant?
 * 	6 = hb	Horizontal Branch
 * 
 * Revision 1.14 2001/05/15 12:18:57  slevy
 * New interface to dynamic-data routines.
 * 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.
 * 
 * Revision 1.13 2001/05/14 15:47:59  slevy
 * Invalidate color/size/threshold sequence numbers so main code will recalc.
 * 
 * Revision 1.12 2001/05/14 08:40:06  slevy
 * kira_draw(): don't do anything if the dynamic data isn't ours.
 * 
 * Revision 1.11 2001/05/12 07:23:05  slevy
 * New generic get-time-range function for dynamic data.
 * 
 * Revision 1.10 2001/04/04 19:23:05  slevy
 * Use portable form of is_open().  Other tidiness.
 * 
 * Revision 1.9 2001/03/30 13:56:07  slevy
 * Rename functions to kira_*.
 * Add framework for incrementally reading paragraphs of input:
 * kira_open(), kira_read_more().
 * Add scraps for maintaining trails, but not enough to work yet.
 * 
 * Revision 1.8 2001/02/04 16:52:38  slevy
 * Use default speck-field names if user doesn't override them
 * (either before or after "kira" reader).
 * 
 * Revision 1.7 2001/02/03 23:37:51  slevy
 * 
 * Oops, now kira_draw needs to ensure we really have something to draw!
 * 
 * Revision 1.6 2001/02/03 15:26:16  slevy
 * 
 * OK, toss those extra 'break's.
 * 
 * Revision 1.5 2001/02/03 15:20:34  slevy
 * 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.
 * 
 * Revision 1.4 2000/12/31 00:25:05  slevy
 * Re-extract whenever kira_set changes something.
 * Add particle tracking.
 * Compute ring sizes correctly, and draw rounder rings.
 * 
 * Revision 1.3 2000/12/30 02:19:30  slevy
 * 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.
 * 
 * Revision 1.2 2000/12/22 01:11:09  slevy
 * Recode to be speedier (use recursion) and to provide more information to partiview:
 * 	[0] worldline index (= kira index for singles, - and unique for others)
 * 	[1] mass
 * 	[2] number of stars (leaf nodes) in clump
 * 		+ 100 if this is a member of an unperturbed binary
 * 	[3] top-level name (small integer, = worldline index for single stars)
 * 	[4] tree address in clump (0=single, 1=root, children of <i> are <2i>,<2i+1>)
 * 
 * Revision 1.1 2000/12/20 16:50:54  slevy
 * Glue code to read starlab (kira) files and interpolate particle positions
 * into partiview internal form.
