picking callbacks!  Fixes broken pick-new-center after detaching view.

Properly compute window ypos from X geometry spec.

to get "detach" & "winsize +X+Y" working.  OK now??

placement of graphics window) and "detach" (sets
placement of GUI widget window).
And, try harder to make detached GUI window behave
properly when resizing.  Not yet though.

They're concatenated.  E.g. "detach fullscreen +20+20"
sets position of control window.

Make "winsize" behave sensibly for already-detached windows
(i.e. don't just leave a small subwindow in a full-screen blank field).

debug, always for vel.

And, ask for velocities (vel=true) when we do preload.

(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.

Add precession.
Add determinant.  Make sure that &basis() returns a
positively-oriented matrix!
More precision in dms output.
Fix bug: qrotbtwn() had the wrong sign!

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.
