Detailed Description

MeshViz Defines a pixel cell of a surface mesh.

A pixel cell is a rectangle of which edges are parallel to X, Y axes.

Nodes and edges are numbered as following :

                        3-----------2   edge 0 = 01
   j                    |           |   edge 1 = 12
                        |           |   edge 2 = 23
   |                    |           |   edge 3 = 30
   |                    |           |
   |                    |           |
   x------> i           0-----------1
