-------------------------------------------+--------------------------------
 Related to 3D stuff, it's become like a good idea to also support TIN and
 Triangle as describted in latest SQL/MM document.

 Triangle as a polygon with only 3 points (so 4 as it's closed like any
 others), and with no internal rings.

 TIN as collection of Triangled connected and well oriented.

 A TIN could be manifold 2 or 3 upon if it's closed.
