* set sub-surface to desynchronized mode
*
* Change the commit behaviour of the sub-surface to
* desynchronized mode, also described as independent or freely
* running mode.
*
* In desynchronized mode, wl_surface.commit on a sub-surface will
* apply the pending state directly, without caching, as happens
* normally with a wl_surface. Calling wl_surface.commit on the
* parent surface has no effect on the sub-surface's wl_surface
* state. This mode allows a sub-surface to be updated on its own.
*
* If cached state exists when wl_surface.commit is called in
* desynchronized mode, the pending state is added to the cached
* state, and applied as a whole. This invalidates the cache.
*
* Note: even if a sub-surface is set to desynchronized, a parent
* sub-surface may override it to behave as synchronized. For
* details, see wl_subsurface.
*
* If a surface's parent surface behaves as desynchronized, then
* the cached state is applied on set_desync.
