Thanks a lot, it's working.
I had to make some more operations (UV-coords translations) because I 
must have the UV coords between 0.0 and 1.0. Blender can deal with 
UV-coords outside this range, but not the application that will use the 
model.

That was my first idea... But a quick look in the code made my thing it 
was not easy task; it seems to me the C function that makes the job is 
well mixed with UI code, but maybe I'm wrong on this - that was really a 
"quick look".
