For coloring by number-of-particles-in-clump.

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.

k2kira, kira2k: translate kira output files between short/long keywords.
tfm.pl: perl geometry/astronomy calculator/library.

Sample partiview Kira-reading script (data2.cf) and Kira data file (data2.out).
Put lots of comments in data2.cf.

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.

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.

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>)

Make ...::format() return count.

Add new "nghosts" field for keeping animation history (trails).

Tidy.

Add default case to ...::printvalue().

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

Add new files kira_parti (Steve McMillan's glue to starlab),
sclock (clock), notify (notification service -- not yet used),
Fl_Log_Slider (log-scaled slider).

Glue code to read starlab (kira) files and interpolate particle positions
into partiview internal form.

Now use worldline.h from ${KIRA}/inc directory rather than
the one hidden deep in the source.

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

Add default rules for .cc (and .C and .cpp) files -- not all versions of make
have them built-in.

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.
