[Papervision3D] backface culling

[Ralph Hauwert]

I'm not sure what would be best yet (nor have I discussed with the  
rest of the team), but I'd feel that the materials should be defined  
on the
objects. Something like this would be my initial idea :

displayobject3d.material = myMaterial, would be the default  
implementation

Or alternatively you'd be able to set :
displayobject3d.frontmaterial = myFrontMaterial;
displayobject3d.backmaterial = myBackMaterial;

How does that sound to you guys ?

Ralph.
