On my various OpenGL branches, there is a patch which disables snapping
to pads on layers which you aren't on. (IE.. only snap to component side
pads if you are on a component copper layer).

I don't think it can be separated too easily from the other patches I
have to improve snapping heuristics. At some point I want to rationalise
the whole stack and see if those changes can be pushed to master.
