[Therion] Additional morphing points (type "extra") explained

[Xavier Pennec]

According to the therion book (p. 25), extra points can also be used 
without LRUD by specifying the distance to either the closest station of 
a specific station, e.g.: point 0.0 0.0 extra -dist 3 -from 2 at mysurvey
I have not tried yet, though.
