Fix knife bug #30764, failure to cut sometimes.
Two bugs: first, the point-in-face function had a bug that made it fail for the xz or yz planes.
Second, in ortho mode, simultaneous linehits need careful sorting.
Also, in orth mode it is somewhat random whether the edges exactly behind the front ones are reported 'hit' by bvh tree, so put in code to prevent cuts along the parallel-to-view faces when not in cut-through mode.
