[Therion] Correcting bad drawings

[Xavier Pennec]

I had the same problem quite a few times, especially to correct old 
drawings that have an error, or to iterate the drawing corrections when 
there is a new loop for instance.

As all the point positions and handle orientations are warped to produce 
the pdf, it seems to me that it could be possible to add a th2 export 
type which would simply outputs the same th2 file with warped coordinates.
Of course, there could be problems with the included images and 
sketches, but that could be skipped if we already have all the other 
objects. Any remark on the possibility of such an export?
