To minimize impact on EventHandler API surface, I'd suggest replacing these
three methods with a single method that returns a reference to the
MockableTimer.  To make it clear this is an abstraction violation I'd explicitly
name it something like 'getActiveInternalTimerForTesting'.

+    void fireActiveIntervalTimer();

     bool adjustGesturePosition(const PlatformGestureEvent&, IntPoint& adjustedPoint);
