HitTestBuffer can be used to make the test point "bigger" to compensate for errors and provide smoother hit-testing. For example, if buffer is 2, a square with a length of 4 units around testPoint will be used to perform the hit-testing.
If more than one object overlaps underneath the test point, the method will return the object on top of the Z-order.
