  <interface name="zcr_cursor_shapes_v1" version="1">
    <description summary="Allows to set the cursor shape">
      Allows to set the semantic cursor shape rather than a surface for a
      pointer cursor.

      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 uinterface version bump.
      Backward incompatible changes are done by bumping the version number in
      the protocol and uinterface 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.

    <request name="set_cursor_shape">
      <description summary="set pointer cursor to the shape">
        Sets the pointer cursor to the specified shape. The server will change
        the cursor graphics based on the specified shape and its graphic assets
        and system condition.

        The "shape" argument needs to be one of the values in cursor_shape_type
        enum. Otherwise invalid_shape error is raised.

        This is similar to wl_pointer::set_cursor request, but this accepts a
        shape instead of contents in the form of a surface.

        The client which do not know this protocol should work as-is, so
        wl_pointer::set_cursor will change the cursor graphics even when it's
        combined with this request; and another invocation of set_cursor_shape
        will change the cursor shape again. This means the last invoked one will
        be used for the actual cursor.
