## @deftypefn {Function File} 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.
