568          This material should be used sparingly, as it may cause the light source calculation to  blow up  if  it is applied to many small surfaces.  
569          This material is only supported for flat surfaces  such  as  <a HREF="#Polygon">polygons</a>  and <a HREF="#Ring">rings</a>.  
570          The arguments are simply the RGB reflectance values, which should be between 0 and 1.

591          It can only be used  to  modify  a  planar  surface

596          The arguments give the coefficient for the redirected light and its direction.
