This event is usually sent as part of a sequence, which begins with
the user placing two fingers on the touchpad, and ends with the user
removing those fingers. @var{dx}, @var{dy}, and @var{angle} will be
@code{0.0} in the first event sent after a sequence begins.

@var{dx} and @var{dy} are reported in imaginary relative units, in
