Due to the "beta"-ness of the software, shared library (0.81), if
provided, is not considered to be "official". 

OpenGL canvas gl.c by default is compiled into the library while
Mesa canvas is not. The OpenGL canvas is compiled using the real
OpenGL header files on the SGIs and emulation using Mesa on
other platforms. So if your platform is not SGI and you have
real OpenGL, you will have to take out gl.o from libforms.a
and re-compile gl.c and re-archive.

There is really no need to use Mesa canvas as Mesa simulates OpenGL 
(including GLX) rather well. By making a link libGL.a to libMesaGL.a, 
you can use the glcanvas with Mesa as if you were using the real OpenGL. 
If your Mesa version is earlier than 1.2.1, you will have to take gl.o out 
of the library and re-compile gl.c and re-archive.

../DEMOS contains a few demo programs that use OpenGL.
