docs: The absolute scale of a pinch gesture, the scale is
  		the division of the current distance between the fingers and
  		the distance at the start of the gesture.
  
  		The scale begins at 1.0, and if e.g. the fingers moved together by
  		50% then the scale will become 0.5, if they move twice as far apart
  		as initially the scale becomes 2.0, etc.
  
  		For gesture events that are of type
  		:attr:`~libinput.constant.EventType.GESTURE_PINCH_BEGIN`, this property
  		returns 1.0.
  
  		For gesture events that are of type
  		:attr:`~libinput.constant.EventType.GESTURE_PINCH_END`, this property
  		returns the scale value of the most recent
  		:attr:`~libinput.constant.EventType.GESTURE_PINCH_UPDATE` event
  		(if any) or 1.0 otherwise.
  
  		For all other events this property raises :exc:`AttributeError`.
  
  		Returns:
  			float: The absolute scale of a pinch gesture.
  		Raises:
  			AttributeError
