Since 0.7 (?) we have included OTF transformation. In the beginning, the code was a bit buggy :-), and I believe that was one of the main reason for turning it off. Now, it's more stable. So, hwat is the reason for being able to turn it off now?
1) Some use-cases handles 'raw' data where a CRS is not meaningful (or maybe unknown even). 2) To skip the OTF code for stability. 3) To skip the OTF code for speed. Measruement tools uses OTF code to be able to calculate on an ellipsoid. Currently, when OTF is off, we don't allow that but usees planimetric calculation only. Is this correct do you think?
