   <description summary="protocol for constraining pointer motions">
     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.

     <description summary="constrain the movement of a pointer">
       The global interface exposing pointer constraining functionality. It
       exposes two requests: lock_pointer for locking the pointer to its
       position, and confine_pointer for locking the pointer to a region.

       The lock_pointer and confine_pointer requests create the objects
       wp_locked_pointer and wp_confined_pointer respectively, and the client can
       use these objects to interact with the lock.

       For any surface, only one lock or confinement may be active across all
       wl_pointer objects of the same seat. If a lock or confinement is requested
       when another lock or confinement is active or requested on the same surface
       and with any of the wl_pointer objects of the same seat, an
       'already_constrained' error will be raised.

     <request name="lock_pointer">
       <description summary="lock pointer to a position">
 	The lock_pointer request lets the client request to disable movements of
 	the virtual pointer (i.e. the cursor), effectively locking the pointer
 	to a position. This request may not take effect immediately; in the
 	future, when the compositor deems implementation-specific constraints
 	are satisfied, the pointer lock will be activated and the compositor
 	sends a locked event.

 	The protocol provides no guarantee that the constraints are ever
 	satisfied, and does not require the compositor to send an error if the
 	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.

 	Note that while a pointer is locked, the wl_pointer objects of the
 	corresponding seat will not emit any wl_pointer.motion events, but
 	relative motion events will still be emitted via wp_relative_pointer
 	objects of the same seat. wl_pointer.axis and wl_pointer.button events
 	are unaffected.

	focus and that the pointer will be within the region passed to the request
	creating this object. It is up to the compositor to decide whether this
	requires some user interaction and if the pointer will warp to within the
	passed region if outside.

	To unconfine the pointer, send the destroy request. This will also destroy
	the wp_confined_pointer object.

	If the compositor decides to unconfine the pointer the unconfined event is
	sent. The wp_confined_pointer object is at this point defunct and should
	be destroyed.

	<request name="set_region">
	<description summary="set a new confine region">
	Set a new region used to confine the pointer.

	The new confine region is double-buffered. The new confine region will
	only take effect when the associated surface gets its pending state
	applied. See wl_surface.commit for details.

	If the confinement is active when the new confinement region is applied
	and the pointer ends up outside of newly applied region, the pointer may
	warped to a position within the new confinement region. If warped, a
	wl_pointer.motion event will be emitted, but no
	wp_relative_pointer.relative_motion event.

	The compositor may also, instead of using the new region, unconfine the
	pointer.

	For details about the confine region, see wp_confined_pointer.
