Fix tokenize() for case of "quoted" or 'quoted' arg strings.

Thanks, Peter.

Allows painting tabular plain-text colormaps
readable with partiview's "cmap" command.

Let @CFLAGS@ tell us where X include-files are.

from a kira data file.

simply enable lighting and use it later, currently in specks_draw_mesh().

not include the new selection stuff Stuart has already implemented.

to interact with double-buffering.
Use preload_pdyn() to precompute trees for each worldbundle.

confirmed that under rh71 the sgml file loads fine in emacs again
(note derived files not committed yet)

don't overwrite args in memory.

mouse samples.  (Actually don't believe delta-t smaller than .15 sec.)

inside #ifdef brackets.

all those maintained by specks_timespecksptr.  We no longer guarantee
that st->curtime is always in range 0..st->ntimes-1, so just yield NULL
for out-of-range references.  New CURDATATIME(fieldname) does it.

Only call parti_parse_args() if non-CAVE.

"spi fast" -> SPI_PF_AUTO.

toggle-button colors to change.  Lets us (barely) see when
inertia and hrdiagram toggles are selected.

Add new per-particle field, "ismember", to show escapees.
