+ * @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
+   * 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.
