Jonathan Westhues ae35b3595c Revamp the edge classification for Booleans. I no longer make a ... separate polygon of coincident (with same or opposite normal) faces; I instead test all the edges against the other shell, and have extended the classify-against-shell stuff to handle those cases. And the normals are now perturbed a bit numerically, to either side of the edge, to distinguish tangency from a coincident surface. This seems to work fairly well, although things still tend to fail when the piecewise linear tolerance is too coarse.
