SpheresContactGeometry::hasShear determines whether shear parameters are
computed; otherwise, you have only the penalty of one if. i.e. almost 0.
We _could_make derived classes etc, but I think it would be too heavy
for this.

Yes, like always. I suggested to Jerome to use python as the portable
way of generating scenes ;-)
