-/**
- * `PanResponder` reconciles several touches into a single gesture. It makes
- * single-touch gestures resilient to extra touches, and can be used to
- * recognize simple multi-touch gestures.
- *
- * It provides a predictable wrapper of the responder handlers provided by the
- * [gesture responder system](docs/gesture-responder-system.html).
- * For each handler, it provides a new `gestureState` object alongside the
- * native event object:
- *
- * ```
- * onPanResponderMove: (event, gestureState) => {}
- * ```
- *
- * A native event is a synthetic touch event with the following form:
- *
- *  - `nativeEvent`
- *      + `changedTouches` - Array of all touch events that have changed since the last event
- *      + `identifier` - The ID of the touch
- *      + `locationX` - The X position of the touch, relative to the element
- *      + `locationY` - The Y position of the touch, relative to the element
- *      + `pageX` - The X position of the touch, relative to the root element
- *      + `pageY` - The Y position of the touch, relative to the root element
- *      + `target` - The node id of the element receiving the touch event
- *      + `timestamp` - A time identifier for the touch, useful for velocity calculation
- *      + `touches` - Array of all current touches on the screen
- *
- * A `gestureState` object has the following:
- *
- *  - `stateID` - ID of the gestureState- persisted as long as there at least
- *     one touch on screen
- *  - `moveX` - the latest screen coordinates of the recently-moved touch
- *  - `moveY` - the latest screen coordinates of the recently-moved touch
- *  - `x0` - the screen coordinates of the responder grant
- *  - `y0` - the screen coordinates of the responder grant
- *  - `dx` - accumulated distance of the gesture since the touch started
- *  - `dy` - accumulated distance of the gesture since the touch started
- *  - `vx` - current velocity of the gesture
- *  - `vy` - current velocity of the gesture
- *  - `numberActiveTouches` - Number of touches currently on screen
- *
- * ### Basic Usage
- *
- * ```
- *   componentWillMount: function() {
- *     this._panResponder = PanResponder.create({
- *       // Ask to be the responder:

- *         // The guesture has started. Show visual feedback so the user knows
- *         // what is happening!
- *
- *         // gestureState.{x,y}0 will be set to zero now
- *       },
- *       onPanResponderMove: (evt, gestureState) => {
- *         // The most recent move distance is gestureState.move{X,Y}
- *
- *         // The accumulated gesture distance since becoming responder is
- *         // gestureState.d{x,y}
- *       },
- *       onPanResponderTerminationRequest: (evt, gestureState) => true,
- *       onPanResponderRelease: (evt, gestureState) => {
- *         // The user has released all touches while this view is the
- *         // responder. This typically means a gesture has succeeded
- *       },
- *       onPanResponderTerminate: (evt, gestureState) => {
- *         // Another component has become the responder, so this gesture
- *         // should be cancelled
- *       },
- *       onShouldBlockNativeResponder: (evt, gestureState) => {
- *         // Returns whether this component should block native components from becoming the JS
- *         // responder. Returns true by default. Is currently only supported on android.
- *         return true;
- *       },
- *     });
- *   },
- *
- *   render: function() {
- *     return (
- *       <View {...this._panResponder.panHandlers} />
- *     );
- *   },
- *
- * ```

-   *
-   * Gesture that calculates cumulative movement over time in a way that just
-   * "does the right thing" for multiple touches. The "right thing" is very
-   * nuanced. When moving two touches in opposite directions, the cumulative
-   * distance is zero in each dimension. When two touches move in parallel five
-   * pixels in the same direction, the cumulative distance is five, not ten. If
-   * two touches start, one moves five in a direction, then stops and the other
-   * touch moves fives in the same direction, the cumulative distance is ten.
-   *
-   * This logic requires a kind of processing of time "clusters" of touch events
-   * so that two touch moves that essentially occur in parallel but move every
-   * other frame respectively, are considered part of the same movement.
-   *
-   * Explanation of some of the non-obvious fields:
-   *
-   * - moveX/moveY: If no move event has been observed, then `(moveX, moveY)` is
-   *   invalid. If a move event has been observed, `(moveX, moveY)` is the
-   *   centroid of the most recently moved "cluster" of active touches.
-   *   (Currently all move have the same timeStamp, but later we should add some
-   *   threshold for what is considered to be "moving"). If a palm is
-   *   accidentally counted as a touch, but a finger is moving greatly, the palm
-   *   will move slightly, but we only want to count the single moving touch.
-   * - x0/y0: Centroid location (non-cumulative) at the time of becoming
-   *   responder.
-   * - dx/dy: Cumulative touch distance - not the same thing as sum of each touch
-   *   distance. Accounts for touch moves that are clustered together in time,
-   *   moving the same direction. Only valid when currently responder (otherwise,
-   *   it only represents the drag distance below the threshold).
-   * - vx/vy: Velocity.

-   * This is nuanced and is necessary. It is incorrect to continuously take all
-   * active *and* recently moved touches, find the centroid, and track how that
-   * result changes over time. Instead, we must take all recently moved
-   * touches, and calculate how the centroid has changed just for those

-   * to (at least) handle the case where the user is moving three fingers, and
-   * then one of the fingers stops but the other two continue.
-   *
-   * This is very different than taking all of the recently moved touches and
-   * storing their centroid as `dx/dy`. For correctness, we must *accumulate
-   * changes* in the centroid of recently moved touches.
-   *
-   * There is also some nuance with how we handle multiple moved touches in a
-   * single event. With the way `ReactNativeEventEmitter` dispatches touches as
-   * individual events, multiple touches generate two 'move' events, each of
-   * them triggering `onResponderMove`. But with the way `PanResponder` works,
-   * all of the gesture inference is performed on the first dispatch, since it
-   * looks at all of the touches (even the ones for which there hasn't been a
-   * native dispatch yet). Therefore, `PanResponder` does not call
-   * `onResponderMove` passed the first dispatch. This diverges from the
-   * typical responder callback pattern (without using `PanResponder`), but
-   * avoids more dispatches than necessary.
