* GLUT Shapes Demo

* Written by Nigel Stewart November 2003

* This program is test harness for the sphere, cone

* and torus shapes in GLUT.

* Spinning wireframe and smooth shaded shapes are

* displayed until the ESC or q key is pressed. The

* number of geometry stacks and slices can be adjusted

* using the + and - keys.
