@Deprecated
public class InvertedRay2D
extends AbstractLine2D
implements Cloneable

Inverted ray is defined from an origin and a direction vector. It is composed of all points satisfying the parametric equation:

x(t) = x0+t*dx
y(t) = y0+t*dy

with t comprised between -INFINITY and 0. This is complementary class to Ray2D.
