It is bit-compatible, so I'd like SWIG to only generate a proxy module  
with "SetPosition(ref Vector3f position)" or whatever
and maybe an "import vector;" via some %{ %} magic, but no wrapper for the  
C++ version of Vector3f.

But I guess this interferes with another issue:
What if I want a C++ struct that is in fact used as POD to be mapped to a  
struct in D (which is always POD)?
