There is a problem with the prism texture : the lower face is of interior_texture for
the counterclockwise prism

In attached pictures: prism was not clipped, lathe was clipped.

And the notion of clockwise is a 3D thing which might still be reworded, something
along: globally, for successive points, compared to the center of all points, when
positive y values decreases, the positive x values increases (?)


right handed system is not only swapping the Z direction, but more often based on Z
being the elevation.
