Of course one could copy the entire source of the IR to make a new 
renderer, but in the case of the cartoon render, a very large amount 
would be the same.  In attempting to subclass a renderer, the problem is 
with the way the attribute set of a geometry is handled.  The 
submit-triangle and submit-trimesh methods need to call 
IRGeometry_Attribute_Handler and IRRenderer_Texture_Postamble, which are 
not available to a plugin subclass.
