+ * A surface is a rectangular area that is displayed on the screen. It |
+ * has a location, size and pixel contents. |
+ * |
+ * The size of a surface (and relative positions on it) is described in |
+ * surface local coordinates, which may differ from the buffer local |
+ * coordinates of the pixel content, in case a buffer_transform or a |
+ * buffer_scale is used. |
+ * |
+ * 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 |
+ * new protocol object that represents the role and adds additional |
+ * 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, |
+ * but it may stop the wl_surface from "playing the role". For instance, if |
+ * a wl_subsurface object is destroyed, the wl_surface it was created for |
+ * 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 |
+ * allowed to use the wl_surface as a cursor (cursor is a different role |
+ * than sub-surface, and role switching is not allowed). |

+ * 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 |
