++ * motions
++ *
++ * @section page_desc_pointer_constraints_unstable_v1 Description
++ *
++ * This protocol specifies a set of interfaces used for adding constraints to
++ * the motion of a pointer. Possible constraints include confining pointer
++ * motions to a given region, or locking it to its current position.
++ *
++ * In order to constrain the pointer, a client must first bind the global
++ * interface "wp_pointer_constraints" which, if a compositor supports pointer
++ * constraints, is exposed by the registry. Using the bound global object, the
++ * client uses the request that corresponds to the type of constraint it wants
++ * to make. See wp_pointer_constraints 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.
++ *
++ * @section page_ifaces_pointer_constraints_unstable_v1 Interfaces
++ * - @subpage page_iface_zwp_pointer_constraints_v1 - constrain the movement of

++ * @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.

++ * 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

++ *
++ * 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

++ * the same physical motion is not guaranteed.
