Prevent entries with identical times
Currently, VelocityTracker adds all MotionEvents with actions DOWN,
MOVE, and POINTER_DOWN. But sometimes these events can have identical
timestamps, for example MOVE and the following POINTER_DOWN.
This breaks algorithms that rely on computing differences between
times of the events. If the difference is zero, and division is
performed, then very large numbers can result from this.
