Where appropriate, update references to geomview license too,
now called COPYING.geomview.

Add Illinois-open-source-license reference to LICENSE.partiview file.

   - MinGW32 (Windows) port, including starlab under Windows
   - incompatible change (bugfix) in sign of crosseyed stereo
	(so positive stereosep values are correctly crosseyed now)

which just draw that one eye's view.  Allows easy
stereo screen snapshotting.

Important: changed sign of crosseyed stereo!
This means that positive stereo-separation values
are now correct for crosseyed (as opposed to walleyed) viewing.
To mark this incompatible change, bumped VERSION to 0.7.

Make --with-nethack a non-default option.
Use deprecated AC_HAVE_LIBRARY to find mingw opengl32 library
because AC_HAVE_LIB fails -- we need a prototype for even
zero-argument functions like glEnd.

Add PORT_OBJS to obj file list.

Scrap unix-specific debug code.

  - supply strcasecmp
  - not supply HUGE
etc.  So make sure HUGE, M_PI, M_LN10 are defined,
along with a few more libm functions used in kira_parti.cc.

with any FLTK-specific modules.  Uses new tag file "libdepended".

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.
