Richard,

        I'm not getting it.  I am running the "shapes" demo with a cube, a tetrahedron, and a torus (all solid) and enabling "GL_CULL_FACE" and not seeing anything improper.  What am I missing?

John Fay has been going through OpenGLUT to get some of the OpenGLUT bug
fixes copied into freeglut.  He didn't mention which bugs he saw fixed
in OpenGLUT that he would be fixing in freeglut, but his post reminded
me of a fairly big one I saw early on with OpenGLUT and fixed months ago.

In freeglut, several of the geometry objects are drawn with reversed
winding on the solid-shaded objects.  All of these were identified and
fixed in OpenGLUT in March, give or take a month I think.  freeglut at
last word still draws several solid-shaded objects incorrectly.

In fact, I think that about the only solid-shaded objects that freeglut
gets correctly are the ones that Nigel fixed (and the cylinder that
he added?) in Fall of 2003.

This is readily apparent if you have the objects animated with back
faces culled.

Just a FYI.
