(1 = scale, 6 = virdir tx ty tz rx ry rz, 7 = same plus scale, 9 = 3x3.)

Need to pass vel=true arg to create_interpolated_tree*.
Hack: pass velocity back to specks in SEPVAL argument for leaf nodes.

Allow multiple requests per connection -- leave connection open
until we get EOF.

Accept T=<scalefactor> as well as T=<16 numbers>.
Report density center both in original and transformed coords.

instead of object coordinates.

Once we pick a license this might change, but
in the mean time, at least the NCSA UIUC origin is noted.

isalpha for Irix 6.5 back-compat.

Return more complete information -- transform etc. -- when
asked for neither speck nor sdb data.

and out of this overstuffed piece of junk.

Removed shmem.o from API

so Matt can make libparti.a.

otherwise just x y z rx ry rz scale; print matrices in %g format for
full precision; accept 7th parameter as scale factor on input
just as we print it on output.

code for reading and displaying particle data. It is used in the
VirDir2 package

-matt

for X-specific stereo code.

Make sure pp_spi_init() is exported where plugins.c can see it.

whether we have a patched FLTK.

but only if FL_STEREO is defined.
Otherwise use old GLX/Unix-specific way.

and refer specifically to Marcus Thiebaux's virdir
since there's now also a Matt Hall version.

check for libfltk_gl.a and .so.  Can't (?) use AC_CHECK_LIB
since it only has C++ entry points.
