/*
* helicoid (gernalized torus) demo
*
* FUNCTION:
* This code provides a very simple example of the helicoid primitive.
* Most of this code is required to set up OpenGL and GLUT, and very
* very little to set up the helix drawer. Don't blink!
*
* HISTORY:
* Written by Linas Vepstas, March 1995
* Copyright (c) 1995 Linas Vepstas <linas@linas.org>
