- * the child surface remains within the visible area's borders, and to
- * specify how the child surface changes its position, such as sliding along
- * an axis, or flipping around a rectangle. These positioner-created rules are

- *
- * See the various requests for details about possible rules.
- *
- * At the time of the request, the compositor makes a copy of the rules
- * specified by the xdg_positioner. Thus, after the request is complete the
- * xdg_positioner object can be destroyed or reused; further changes to the
- * object will have no effect on previous usages.
- *
- * For an xdg_positioner object to be considered complete, it must have a
- * non-zero size set by set_size, and a non-zero anchor rectangle set by
- * set_anchor_rect. Passing an incomplete xdg_positioner object when

- *
- * An interface that may be implemented by a wl_surface, for
- * implementations that provide a desktop-style user interface.
- *
- * It provides a base set of functionality required to construct user
- * interface elements requiring management by the compositor, such as
- * toplevel windows, menus, etc. The types of functionality are split into
- * xdg_surface roles.
- *
- * Creating an xdg_surface does not set the role for a wl_surface. In order
- * to map an xdg_surface, the client must create a role-specific object
- * using, e.g., get_toplevel, get_popup. The wl_surface for any given
- * xdg_surface can have at most one role, and may not be assigned any role
- * not based on xdg_surface.
- *
- * A role must be assigned before any other requests are made to the
- * xdg_surface object.
- *
- * The client must call wl_surface.commit on the corresponding wl_surface
- * for the xdg_surface state to take effect.
- *
- * Creating an xdg_surface from a wl_surface which has a buffer attached or
- * committed is a client error, and any attempts by a client to attach or
- * manipulate a buffer prior to the first xdg_surface.configure call must
- * also be treated as errors.
- *
- * After creating a role-specific object and setting it up (e.g. by sending
- * the title, app ID, size constraints, parent, etc), the client must
- * perform an initial commit without any buffer attached. The compositor
- * will reply with initial wl_surface state such as
- * wl_surface.preferred_buffer_scale followed by an xdg_surface.configure
- * event. The client must acknowledge it and is then allowed to attach a
- * buffer to map the surface.
- *
- * Mapping an xdg_surface-based role surface is defined as making it
- * possible for the surface to be shown by the compositor. Note that
- * a mapped surface is not guaranteed to be visible once it is mapped.
- *
- * For an xdg_surface to be mapped by the compositor, the following
- * conditions must be met:
- * (1) the client has assigned an xdg_surface-based role to the surface
- * (2) the client has set and committed the xdg_surface state and the
- * role-dependent state to the surface
- * (3) the client has committed a buffer to the surface
- *
- * A newly-unmapped surface is considered to have met condition (1) out
- * of the 3 required conditions for mapping a surface if its role surface
- * has not been destroyed, i.e. the client must perform the initial commit
- * again before attaching a buffer.

-	 * had an explicit grab.

-	 * dismissed, this popup will be immediately dismissed. If the
-	 * parent is a popup that did not take an explicit grab, an error
-	 * will be raised.

-	 * During a popup grab, the client owning the grab will receive
-	 * pointer and touch events for all their surfaces as normal
-	 * (similar to an "owner-events" grab in X11 parlance), while the
