28 This base is class allows to write simple trackers that deal with single
29 drag gestures. It is *not* suitables for multi-state trackers where various
30 mouse operations need to be handled.
31
32 In order to write such a tracker:
33 - subclass this class
34 - you may store the initial click/touch position in the constructor
35 - implement PointerMove to react to pointer/touch events
36 - implement Cancel to restore the state at initial tracker creation time
