Local axis constraint external call. Had to do it in a very hackish way which highlight a design problem in the code. To solve it (and would solve other problems too), we'd have to split off the initialisation function. Not terribly hard to do but I'm overwhelmed with work...

Push/Pull had a problem with constraints enabling/disabling. Fixed

Restablished infinite line for constraint draw (when not using manipulator) as discussed in meeting.
