Comment (by dbaston):

 We only need one version of the iterator, but we could have multiple
 versions of these two functions:
 {{{
 int lwiterator_next(LWITERATOR* s, POINT4D* p);
 int lwiterator_peek(LWITERATOR* s, POINT4D* p);
 }}}

 Or we could (as I've done so far) provide only 4D points, and let the user
 convert them as they wish.
