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.
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.
