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

* sub-surface's size and position are not limited to that of the parent.
* Particularly, a sub-surface is not automatically clipped to its
* parent's area.
*
* A sub-surface becomes mapped, when a non-NULL wl_buffer is applied
* and the parent surface is mapped. The order of which one happens
* first is irrelevant. A sub-surface is hidden if the parent becomes
* hidden, or if a NULL wl_buffer is applied. These rules apply
* recursively through the tree of surfaces.
*
* The behaviour of a wl_surface.commit request on a sub-surface
* depends on the sub-surface's mode. The possible modes are
* synchronized and desynchronized, see methods
* wl_subsurface.set_sync and wl_subsurface.set_desync. Synchronized
* mode caches the wl_surface state to be applied when the parent's
* state gets applied, and desynchronized mode applies the pending
* wl_surface state directly. A sub-surface is initially in the
* synchronized mode.
*
* Sub-surfaces have also other kind of state, which is managed by
* wl_subsurface requests, as opposed to wl_surface requests. This
* state includes the sub-surface position relative to the parent
* surface (wl_subsurface.set_position), and the stacking order of
* the parent and its sub-surfaces (wl_subsurface.place_above and
* .place_below). This state is applied when the parent surface's
* wl_surface state is applied, regardless of the sub-surface's mode.
* As the exception, set_sync and set_desync are effective immediately.
*
* The main surface can be thought to be always in desynchronized mode,
* since it does not have a parent in the sub-surfaces sense.
*
* Even if a sub-surface is in desynchronized mode, it will behave as
* in synchronized mode, if its parent surface behaves as in
* synchronized mode. This rule is applied recursively throughout the
* tree of surfaces. This means, that one can set a sub-surface into
* synchronized mode, and then assume that all its child and grand-child
* sub-surfaces are synchronized, too, without explicitly setting them.
*
* If the wl_surface associated with the wl_subsurface is destroyed, the
* wl_subsurface object becomes inert. Note, that destroying either object
* takes effect immediately. If you need to synchronize the removal
* of a sub-surface to the parent surface update, unmap the sub-surface
* first by attaching a NULL wl_buffer, update parent, and then destroy
* the sub-surface.
*
* If the parent wl_surface object is destroyed, the sub-surface is

* must be an integer multiple of the buffer_scale.
*
* The x and y arguments specify the location of the new pending
* buffer's upper left corner, relative to the current buffer's upper
* left corner, in surface-local coordinates. In other words, the
* x and y, combined with the new surface size define in which

*
* 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.
*
* Destroying the wl_buffer after wl_buffer.release does not change
* the surface contents. However, if the client destroys the
* wl_buffer before receiving the wl_buffer.release event, the surface
* contents become undefined immediately.
*
* If wl_surface.attach is sent with a NULL wl_buffer, the
