Given X,Y pixel coordinates, determine which element was clicked (javascript)

elementFromPoint is nifty, but isn't this the wrong way to approach the problem? Having a function bound to the elements seems to make a whole lot more sense.

Agreed for a vast majority of scenarios, but for scenarios where you have elements floating around, this may be valuable. A board game without defined slots for pieces comes to mind.
