Jonathan Westhues	3da334028e	Let's use the direction cosines (dot product of unit vectors), not the arbitrary-magnitude dot product, to classify regions (inside, outside, coincident) of surfaces against each other. That lets me always perturb the point for the normals (inside and outside the edge) by just a chord tolerance, and nothing bad happens as that distance varies over a few orders of magnitude.

Split line-surface intersection and shell raycasting stuff into its
