               Install a private colormap for the window.

       -visual visual

       -fps    Display the current frame rate, CPU load, and polygon count.

               Show a textured tunnel. This is the default.

               Disables texturing the animation.

       -wire   Draw a wireframe rendition of the tunnel.


       DISPLAY to get the default host and display number.
