| + * | 
| + * A surface without a "role" is fairly useless, a compositor does not know | 
| + * where, when or how to present it. The role is the purpose of a | 
| + * wl_surface. Examples of roles are a cursor for a pointer (as set by | 
| + * wl_pointer.set_cursor), a drag icon (wl_data_device.start_drag), a | 
| + * sub-surface (wl_subcompositor.get_subsurface), and a window as defined | 
| + * by a shell protocol (e.g. wl_shell.get_shell_surface). | 
| + * | 
| + * A surface can have only one role at a time. Initially a wl_surface does | 
| + * not have a role. Once a wl_surface is given a role, it is set | 
| + * permanently for the whole lifetime of the wl_surface object. Giving the | 
| + * current role again is allowed, unless explicitly forbidden by the | 
| + * relevant interface specification. | 
| + * | 
| + * Surface roles are given by requests in other interfaces such as | 
| + * wl_pointer.set_cursor. The request should explicitly mention that this | 
| + * request gives a role to a wl_surface. Often, this request also creates a |

| + * functionality to wl_surface. When a client wants to destroy a | 
| + * wl_surface, they must destroy this 'role object' before the wl_surface. | 
| + * | 
| + * Destroying the role object does not remove the role from the wl_surface, |

| + * will be unmapped and forget its position and z-order. It is allowed to | 
| + * create a wl_subsurface for the same wl_surface again, but it is not |

| + * 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 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. |
