See #4652. Fix bug where auto-detection of a false origin could be in…

…correct

We were incorrectly multiplying a shape matrix in SI units with a vertex in project units. We also didn't do a final check whether or not that final resultant coordinate was far away or not (for example, origin and vertex can cancel each other out)
