I'm having the geometry viewer display a GEOM_POLYHEDRON geometry of a
double headed arrow:
  /      \
 /|______|\
/          \       (wow, with ascii graphics like this, why use AVS?;^)
\  ______  /
 \|      |/
  \      /

When I set the render mode to "lines", I observe the expected result in 
the geometry viewer window: I see an outline of a double headed arrow.

HOWEVER, when I set the render mode to "no_light", I don't get a solid 
double headed arrow like I want.  I get something like this:
           
  /     /\
 /|___ /  \
/          \ 
\    ____  /
 \  /    |/
  \/     /
  

How can I get a solid double headed arrow like I want?  I've tried other
rendering modes but I don't get a solid double headed arrow.

Thanks.
