The bug was not that the color of some faces changed with respect to
the view angle, but that the hidden color was wrongly ascribed to
some external visible faces.<br>
By the way, the way Scilab ascribes the hidden color looks not
documented. It follows the "screw" rule to set the external and
internal faces. So, the order vertices are provided matters. I did
not see it described in any page.<br>
