The GL Utilities module is a partial implementation of the
GLU library. This module only contains functions that someone
at some point actually needed to get his work done. If you
need a GLU function that isn't in here, copy the C code from
the GLU library (Mesa was used last time), tweak it so that
it compiles as Pike code and then check it in into the CVS.

examples or code.
