when the event occured, @var{dx} is the change between the horizontal
positions of the fingers since the last event in the same sequence,
(@pxref{Click Events}) that provides the position of the mouse pointer
when the event occurred, @var{dx} is the change in the horizontal
distance between the fingers since the last event in the same sequence,
@var{dy} is the vertical movement of the fingers since the last event
in the same sequence, @var{scale} is the ratio of the current distance
between the fingers and the distance at the start of the sequence, and
