"Perfectly" I mean that one end of the arrow hits the edge of one shape and
the other end hits the edge of the second shape... i thought there was
another way to do it, other then manually
If you get the end or the Arrow close to the other object and release it
will "snap to" it. But you need to get it close, you can't just drop it
off in the middle of nowhere and expect it to "home in".
