* props:
* direction: a vector that indicates the direction of the intended swipe
* threshold: the minimum distance in pixels the swipe has moved on `direction'
* for swipe-finished() to have a non-zero sign
* perpendicularTolerance: see gesture_service
*
* Events:
* preview-requested(offsets)
* Emitted when the pointer has moved.
* offsets: the offsets from the start of the swipe to the current cursor position
*
* swipe-canceled()
* Emitted when the swipe has been canceled due to a pointercancel event.
*
* swipe-finished(sign: 0|-1|1)
* Emitted when the swipe has finished.
* sign: if the swipe does not meet the threshold, 0
* if the swipe meets the threshold in the positive direction, 1
* if the swipe meets the threshold in the negative direction, -1
*
* swipeless-clicked()
* Emitted when there is a click without swipe.
* This and swipe-finished() cannot be emitted for the same pointerup event.
