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

* @section page_iface_wl_subsurface_desc Description
*
* An additional interface to a wl_surface object, which has been
* made a sub-surface. A sub-surface has one parent surface. A
* 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
* unmapped.

*
* The client may specify a method to resolve a size conflict

*
* The framerate parameter is used only when the method is set

* the surface, either via a direct scaling operation or a change of
* the output mode. This will override any kind of output scaling, so
* that mapping a surface with a buffer size equal to the mode can
* fill the screen independent of buffer_scale.
*
* A method of "fill" means we don't scale up the buffer, however
* any output scale is applied. This means that you may run into
* an edge case where the application maps a buffer with the same
* size of the output mode but buffer_scale 1 (thus making a
* surface larger than the output). In this case it is allowed to
* downscale the results to fit the screen.
