    <event name="axis">
      <description summary="axis event">
        Scroll and other axis notifications.

        For scroll events (vertical and horizontal scroll axes), the
        value parameter is the length of a vector along the specified
        axis in a coordinate space identical to those of motion events,
        representing a relative movement along the specified axis.

        For devices that support movements non-parallel to axes multiple
        axis events will be emitted.

        When applicable, for example for touch pads, the server can
        choose to emit scroll events where the motion vector is
        equivalent to a motion event vector.

        When applicable, a client can transform its content relative to the
        scroll distance.

    <event name="axis_value120">

        Discrete high-resolution scroll information.

        This event carries high-resolution wheel scroll information,
        with each multiple of 120 representing one logical scroll step
        (a wheel detent). For example, an axis_value120 of 30 is one quarter of
        a logical scroll step in the positive direction, a value120 of
        -240 are two logical scroll steps in the negative direction within the
        same hardware event.
        Clients that rely on discrete scrolling should accumulate the
        value120 to multiples of 120 before processing the event.

        The value120 must not be zero.

    <event name="axis_stop">
      <description summary="axis stop event">
        Stop notification for scroll and other axes.

        A axis_stop event can be sent to notify a client that the
        axis sequence has terminated.
        This enables the client to implement kinetic scrolling.

        The timestamp is to be interpreted identical to the timestamp in the
        axis event. The timestamp value may be the same as a
        preceding axis event.

    <event name="frame">
      <description summary="end of a pointer event sequence">
        Indicates the end of a set of events that logically belong together.
        A client is expected to accumulate the data in all events within the
        frame before proceeding.

        All pointer events before a frame event belong
        logically together. For example, in a diagonal scroll motion the
        compositor will two axis events (horizontal and vertical) and
        a frame event. The client may use this information to
        calculate a diagonal vector for scrolling.

        When multiple axis events occur within the same frame,
        the motion vector is the combined motion of all events.
        When a axis and a axis_stop event occur within
        the same frame, this indicates that axis movement in one axis has
        stopped but continues in the other axis.
        When multiple axis_stop events occur within the same
        frame, this indicates that these axes stopped in the same instance.

        A frame event is sent for every logical event group,
        even if the group only contains a single pointer event.
        Specifically, a client may get a sequence: motion, frame, button,
        frame, axis, frame, axis_stop, frame.
