LINES2D  Description of functions operating on planar lines.

   The term 'line' refers to a planar straight line, which is an unbounded
   curve. Line segments defined between 2 points, which are bounded, are
   called 'edge', and are presented in file 'edges2d'.

   A straight line is defined by a point (its origin), and a vector (its
   direction). The parameters are bundled into a 1-by-4 row vector:
   LINE = [x0 y0 dx dy];

   A line contains all points (x,y) such that:
       x = x0 + t*dx
       y = y0 + t*dy;
   for all t between -infinity and +infinity.
