A possible tweak?

Hi Burr, I guess it would also be possible to implicitly disable only axis snap when in this kind of planar projection point pick type situation in the 3D view.

That may be feasible, if it is only axis snap that is disabled it would still allow the other kinds of snap projections like I showed previously.

I'll think about that a bit more tommorrow.
