Avoid PanGesture circular buffer overflow

[problem]     ScrollView sometimes moves in the wrong direction.
[cause]       Motion events received in excess of PanGesture PAN_GESTURE_HISTORY limit,
before the update-thread can process in the correct order.
[solution]    Increase PAN_GESTURE_HISTORY value.
