Drag class

Interface for objects that receive updates about drags.

This interface is used in various ways. For example, MultiDragGestureRecognizer uses it to update its clients when it recognizes a gesture. Similarly, the scrolling infrastructure in the widgets library uses it to notify the DragScrollActivity when the user drags the scrollable.
