+
+	For a wl_pointer.axis event, the wl_pointer.axis_relative_direction
+	event specifies the movement direction of the entity causing the
+	wl_pointer.axis event. For example:
+	- if a user's fingers on a touchpad move down and this
+	  causes a wl_pointer.axis vertical_scroll down event, the physical
+	  direction is 'identical'
+	- if a user's fingers on a touchpad move down and this causes a
+	  wl_pointer.axis vertical_scroll up scroll up event ('natural
+	  scrolling'), the physical direction is 'inverted'.
+
+	A client may use this information to adjust scroll motion of
+	components. Specifically, enabling natural scrolling causes the
+	content to change direction compared to traditional scrolling.
+	Some widgets like volume control sliders should usually match the
+	physical direction regardless of whether natural scrolling is
+	active. This event enables clients to match the scroll direction of
+	a widget to the physical direction.
+
+	This event does not occur on its own, it is coupled with a

+	axis number within the same wl_pointer.frame. Note that the protocol
+	allows for other events to occur between the axis_relative_direction
+	and its coupled axis event.
+
+	The axis number is identical to the axis number in the associated
