I have tried Ubuntu 18.04 and yadedaily and it worked.
Concerning the biggest area polygon, I would start with some simple
"testing" 2D situations.
Consider a "ground", large enough polyhedron with xy surface.
Consider a prism coming to ground. In the beginning, The intersection is "flat
square", the largest section is perpendicular to z axis, as expected.

Consider a "needle", a very sharp pyramid or a "long" prism with z axis. Then
the intersection is a subshape with z axis and the contact normal is expected
to be also z axis.
But it is the direction with **least** section area..
The largest area is perpendicular to z axis..

So it seems the biggest area polygon is not universally good..
BUT, it just a quick brainstorming, maybe there is some mistake in my
assumptions or there exist some easy fix :-)
