this is what I meant :-)

> two opposite points of the overlap volume, along the normal direction,
passing from the contact point, and calculate the
equivalentPenetrationDepth as the distance of these points.

then it would be needed to distinguish equivalentPenetrationDepth and
this "estimatedPEnetrationDepth"
