It just occurred to me: If you have a graphic element, such as a triangle or rectangle, etc., and you want to know if a point lies inside it or outside it, you would want a method such as this one.
But I think you would need to apply it relative to a vertex of the polygon in question, since it assumes a ray starting at (0@0) to a given point (i.e., an adjoining vertex). -- Sent from: http://forum.world.st/Pharo-Smalltalk-Developers-f1294837.html
