EDGES2D  Description of functions operating on planar edges.

   An edge is represented by the coordinate of its extremities:
   EDGE = [X1 Y1 X2 Y2];

   Centered edges are sometimes used (for example for representing main
   axes of an ellipse or an oriented box). Centered edges are represented
   by their center, their length, and their orientation (counted in
   degrees and counter-clockwise).
   CEDGE = [XC YC LEN THETA];

   A set of edges is represented by a N-by-4 array, each row representing
   an edge.
