+ * @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.
+ *

+ * to activate. If the region is null the surface input region is used.

+ * @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.
