Changed the directory structure of the src
Added some party simulation stuff

the validity test.

Lets TextureHook set texture matrix to determine how to map the
video texture.

mode.  Rather than having text be oriented per-graphics-window,
we choose the orientation of the master pipe.

this enables multisampling if FLTK and the hardware support it.

so manually setting OPT can override what they do.

No need to mention cat_modelutil.cc; cat_model.cc #include's it.

and/or vertex normals.

Since some partiview files are adapted from geomview,
this should have been here all along.

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".
