IPointableElement Interface

This interface specifies that an implementing type is a recipient of PointerEvents and is thus conceptually something, "to which one can point." Note that IPointableElement is (as an IPointable) both an originator of and a consumer of PointerEvents; this manifests the common Interaction SDK pattern that PointerEvents are created by the instrument which does the pointing, are received by the target to which one points, and are then forwarded by that target to additional consumers.
