The problem is that Alpha is planned to be used for flexibility in  
sculpties, and there are already experimental version of the Open  
Source viewer testing this.

It would probably be better to add a flag (like the flag proposed for  
indicating flexible sculpties) indicating that <0,0,0> was not part of  
the geometry.
