  2.  * GLUT Shapes Demo
  3.  *
  4.  * Written by Nigel Stewart November 2003
  5.  *
  6.  * This program is test harness for the sphere, cone
  7.  * and torus shapes in GLUT.
  8.  *
  9.  * Spinning wireframe and smooth shaded shapes are
  10.  * displayed until the ESC or q key is pressed.  The
  11.  * number of geometry stacks and slices can be adjusted
  12.  * using the + and - keys.
