	 * be replaced with using the separate wl_surface.offset request.
	 *
	 * When the bound wl_surface version is 5 or higher, passing any
	 * non-zero x or y is a protocol violation, and will result in an
	 * 'invalid_offset' error being raised. The x and y arguments are
	 * ignored and do not change the pending state. To achieve
	 * equivalent semantics, use wl_surface.offset.
	 *
	 * Surface contents are double-buffered state, see
	 * wl_surface.commit.
	 *
	 * The initial surface contents are void; there is no content.
	 * wl_surface.attach assigns the given wl_buffer as the pending
	 * wl_buffer. wl_surface.commit makes the pending wl_buffer the new
	 * surface contents, and the size of the surface becomes the size
	 * calculated from the wl_buffer, as described above. After commit,
	 * there is no pending buffer until the next attach.
	 *
	 * Committing a pending wl_buffer allows the compositor to read the
	 * pixels in the wl_buffer. The compositor may access the pixels at
	 * any time after the wl_surface.commit request. When the
	 * compositor will not access the pixels anymore, it will send the
	 * wl_buffer.release event. Only after receiving wl_buffer.release,
	 * the client may reuse the wl_buffer. A wl_buffer that has been
	 * attached and then replaced by another attach instead of
	 * committed will not receive a release event, and is not used by
	 * the compositor.
	 *
	 * If a pending wl_buffer has been committed to more than one
	 * wl_surface, the delivery of wl_buffer.release events becomes
	 * undefined. A well behaved client should not rely on
	 * wl_buffer.release events in this case. Alternatively, a client
	 * could create multiple wl_buffer objects from the same backing
	 * storage or use wp_linux_buffer_release.
	 *
	 * Destroying the wl_buffer after wl_buffer.release does not change
	 * the surface contents. Destroying the wl_buffer before
	 * wl_buffer.release is allowed as long as the underlying buffer
	 * storage isn't re-used (this can happen e.g. on client process
	 * termination). However, if the client destroys the wl_buffer
	 * before receiving the wl_buffer.release event and mutates the
	 * underlying buffer storage, the surface contents become undefined
	 * immediately.
	 *
	 * If wl_surface.attach is sent with a NULL wl_buffer, the
	 * following wl_surface.commit will remove the surface content.
	 *
	 * If a pending wl_buffer has been destroyed, the result is not
	 * specified. Many compositors are known to remove the surface
	 * content on the following wl_surface.commit, but this behaviour
	 * is not universal. Clients seeking to maximise compatibility
