I'll close this one as it doesn't really make sense to snap a point against a line, for the sole purpose that it's NOT POSSIBLE in a finite space. Eventually you'd be snapping the line to the projected point on it. What I mean is that you can't obtain a "point-on-line" w/out actually adding a vertex to the line.
