Avoid breaking up the clipHullHull kernel, it ruins performance. Unfortunately, Mac OSX still requires it.

Add the contact point from MPR, in addition to SAT/clipping contacts. Added a new kernel to clear/reset the number of contacts in pairs (stored in the z component)
Always sample unit sphere directions, if there are more edge-edge combinations than unit sphere directions (162 by default)
