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.
