/**
* Pan Gesture Event Processing:
*
- * When we receive a pinch gesture event, we do the following:
- * - Determine the hot actor underneath the current position of the pan gesture event.
- * - Determine whether this actor is, or is a child of, the actor(s) attached to any of the
- * detectors.
- * - Emit the gesture when all the above conditions are met.
+ * When we receive a pan gesture event, we do the following:
+ * - Find the actor that requires a pan where the pan started from (i.e. the down position).
+ * - Emit the gesture if the event satisfies the detector conditions.
*
* The above is only checked when our gesture starts. We continue sending the pan gesture to the
* same actor and detector until the pan ends or is cancelled.
* Create a pan gesture processor.
* @param[in] stage The stage.
* @param[in] gestureManager The gesture manager
