Here's a real hack:  turn on "Outline Gouraud" mode (you need to be 
in the software renderer for this to work) and set the object color
to be the same as the background.  This will create an image with 
"hidden lines" the expensive way. 

On a distantly related note, I was introduced to Henri Gouraud at
SIGGRAPH last week and when asked "Do you know Henri Gouraud?", I was
so overwhelmed by being in the presence of greatness that all I 
could figure out to say was "No, but I've used your interpolation
method!"  

I don't think he was impressed.
