Re: Geometry building and C++ UDF library

i pushed things a bit further and realized that :

- my problem was solved by adding :
set_data_ptr(wkb, len);
at the end of "init_from_wkb" functions. indeed m_data was never affected; i can't realize if it was on purpose or not... but i obviously need it to be correct to be able to use geometries.

- exterior_ring is not as useful as i expected... since it just returns the first linestring in a polygon without any geometric computation. i guess it's just work in progress but i didn't realize it earlier :)

if it may help someone else....
