Quick 30 second thought that makes a big difference for pure
vertical/horizontal gradients. It's possible that there should
be some epsilon in the tests, to handle round-off errors in
90 degree rotations and the like, maybe something like
fabs (p2.x - p1.x) < EPSILON * fabs (p2.y - p1.y)
?
Regards,
Owen
