-   Robust reflections use stenciling.  Robust projected shadows

-   should realize that neither stenciling nor polygon offset are 
-   supported by Direct3D, so these real-time rendering algorithms
-   are only really viable with OpenGL. 
-   
-   The program has modes for disabling the stenciling and polygon
-   offset uses.  It is worth running this example with these features
-   toggled off so you can see the sort of artifacts that result.
-   
-   Notice that the floor texturing, reflections, and shadowing
-   all co-exist properly. */
