Fair enough. Only trouble is that I'm not really qualified to assess the 
impact of the approach, and whether Tamas' suggestion is the right way 
to go about it. Or even at this stage how to describe Tamas' approach... 

This seems to me like a big chunk that's missing from the OGR C 
interface, but maybe I'm just missing some aspect of how the C API can 
be used. For my money, I'm thinking that this functionality should be 
added into the basic C API (and thence picked up from there by SWIG et 
al). Don't people using the C API to OGR want more geometry specific 
functionality? I still haven't worked out how one can deal with all but 
the simplest geometries through the C interface - for instance 
identifying inner and outer rings of a polygon.
