       This draws the three-dimensional variant of the recursive Sierpinski triangle fractal, using GL.

DISPLAY to get the default host and display number.

       XENVIRONMENT
               to  get  the  name  of  a  resource  file  that  overrides  the  global  resources  stored in the
               RESOURCE_MANAGER property.

       XSCREENSAVER_WINDOW
               The window ID to use with --root.

--visualvisual
               Specify which visual to use.  Legal values are the name of a  visual  class,  or  the  id  number
               (decimal or hex) of a specific visual.

       --window
               Draw on a newly-created window.  This is the default.

       --root  Draw on the root window.

       --window-idnumber
               Draw on the specified window.

       --delaynumber
               Per-frame delay, in microseconds.  Default: 20000 (0.02 seconds.).

       --speednumber
               Number of frames before changing shape.  Default: 150.

       --depthnumber
               Max depth to descend.  Default: 5.  You probably don't have enough memory for 6.

       --wireframe
               Render in wireframe instead of solid.

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