lineToEdge

LINETOEDGE Convert a straight line to a finite edge.

   EDGE = lineToEdge(LINE)
   Returns the edge with same origin as the line LINE, and with second
   extremity corresponding to the addition of line origin and direction.
   LINE is represented as [X0 Y0  DX DY]
   EDGE is represented as [X1 Y1  X2 Y2]

   Example
     line = [3 4  1 2];
     edge = lineToEdge(line)
     edge =
          3   4   4   6
