 * object' before the wl_surface.

 * Destroying the role object does not remove the role from the

 * For instance, if a wl_subsurface object is destroyed, the wl_surface

 * x and y, combined with the new surface size define in which
 * directions the surface's size changes. Setting anything other than 0
 * as x and y arguments is discouraged, and should instead 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. 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.
