%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 different parameters are bundled into a 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.
