Looking at my previous post I felt the isBehindLine function served it's purpose, but if I get a more complicated problem similar to a raycasting test with imaginary ray of arbitrary width I would need to know more information where a Point is relevant to a Segment.

The "whereAboutSegment" function will return a String this time, with more detailed info of the Point's where-a-abouts instead of just knowing if its behind a line.

After writing a function to test intersections of a line to a polygon, another problem came up where I needed
to test an intersection of a line to a curve. I'm sure there is a library someone has wrote that could do this but there is some fun in figuring out puzzles.
There was a recent comment about curves and intersections so I decided to go ahead an post what I attempted.
I feel using a loop is expensive, but it's all I can think of doing for this, similar to the lineIntersectPoly function.

"Drag and Drop" behavior is easy to do in ActionScript, but sometimes it would be cooler if you could limit or constrain the dragging movement of an object to a line. This opens the door for implementing
more creative interaction design...
