Returns the rotational offset of the geom in local coordinates.
If the geom has no offset, this function returns the identity
matrix.
@param geom the geom to query.
@returns A pointer to the geom's offset rotation matrix.
@remarks The returned value is a pointer to the geom's internal
data structure. It is valid until any changes are made
to the geom.
