++ * @page page_pointer_constraints_unstable_v1 The
++ * pointer_constraints_unstable_v1 protocol protocol for constraining pointer
++ * 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
++ * a pointer
++ * - @subpage page_iface_zwp_locked_pointer_v1 - receive relative pointer motion

++ * future, when the compositor deems implementation-specific constraints

++ * sends a locked event.
++ *

++ * constraints cannot ever be satisfied. It is thus possible to request a
++ * lock that will never activate.
++ *
++ * There may not be another pointer constraint of any kind requested or
++ * active on the surface for any of the wl_pointer objects of the seat of
++ * the passed pointer when requesting a lock. If there is, an error will be
++ * raised. See general pointer lock documentation for more details.
++ *
++ * The intersection of the region passed with this request and the input
++ * region of the surface is used to determine where the pointer must be
++ * in order for the lock to activate. It is up to the compositor whether to
++ * warp the pointer or require some kind of user interaction for the lock
++ * to activate. If the region is null the surface input region is used.
++ *
++ * A surface may receive pointer focus without the lock being activated.
++ *
++ * The request creates a new object wp_locked_pointer which is used to
++ * interact with the lock as well as receive updates about its state. See
++ * the the description of wp_locked_pointer for further information.

++ * @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.
