/**
 * @page page_relative_pointer_unstable_v1 The relative_pointer_unstable_v1 protocol
 * protocol for relative pointer motion events
 *
 * @section page_desc_relative_pointer_unstable_v1 Description
 *
 * This protocol specifies a set of interfaces used for making clients able to
 * receive relative pointer events not obstructed by barriers (such as the
 * monitor edge or other pointer barriers).
 *
 * To start receiving relative pointer events, a client must first bind the
 * global interface "wp_relative_pointer_manager" which, if a compositor
 * supports relative pointer motion events, is exposed by the registry. After
 * having created the relative pointer manager proxy object, the client uses
 * it to create the actual relative pointer object using the
 * "get_relative_pointer" request given a wl_pointer. The relative pointer
 * motion events will then, when applicable, be transmitted via the proxy of
 * the newly created relative pointer object. See the documentation of the
 * relative pointer interface for more details.
 *
 * Warning! The protocol described in this file is experimental and backward
 * incompatible changes may be made. Backward compatible changes may be added
 * together with the corresponding interface version bump. Backward
 * incompatible changes are done by bumping the version number in the protocol
 * and interface names and resetting the interface version. Once the protocol
 * is to be declared stable, the 'z' prefix and the version number in the
 * protocol and interface names are removed and the interface version number is
 * reset.

	 * Relative x/y pointer motion from the pointer of the seat
	 * associated with this object.
	 *
	 * A relative motion is in the same dimension as regular wl_pointer
	 * motion events, except they do not represent an absolute
	 * position. For example, moving a pointer from (x, y) to (x', y')
	 * would have the equivalent relative motion (x' - x, y' - y). If a
	 * pointer motion caused the absolute pointer position to be
	 * clipped by for example the edge of the monitor, the relative
	 * motion is unaffected by the clipping and will represent the
	 * unclipped motion.
	 *
	 * This event also contains non-accelerated motion deltas. The
	 * non-accelerated delta is, when applicable, the regular pointer
	 * motion delta as it was before having applied motion acceleration
	 * and other transformations such as normalization.
	 *
	 * Note that the non-accelerated delta does not represent 'raw'
	 * events as they were read from some device. Pointer motion
	 * acceleration is device- and configuration-specific and
	 * non-accelerated deltas and accelerated deltas may have the same
	 * value on some devices.
	 *
	 * Relative motions are not coupled to wl_pointer.motion events,
	 * and can be sent in combination with such events, but also
	 * independently. There may also be scenarios where
	 * wl_pointer.motion is sent, but there is no relative motion. The
	 * order of an absolute and relative motion event originating from
	 * the same physical motion is not guaranteed.
	 *
	 * If the client needs button events or focus state, it can receive
	 * them from a wl_pointer object of the same seat that the
	 * wp_relative_pointer object is associated with.
