searchableSurface using multiple slightly shifted underlying surfaces to make sure pierces don't go through gaps:

shift test vector with two small vectors (of size gap_) perpendicular to the original. Test with + and - this vector. Only if both register a hit is it seen as one.
extend the test vector slightly (with SMALL) to account for numerical inaccuracies.
