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.
For a surface to be mapped by the compositor, the following conditions must be met: (1) the client has assigned a 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 and (3) the client has committed a buffer to the surface.

When a configure event is received, if a client commits the surface in response to the configure event, then the client must make an ack_configure request sometime before the commit request, passing along the serial of the configure event.
For instance, for toplevel surfaces the compositor might use this information to move a surface to the top left only when the client has drawn itself for the maximized or fullscreen state.
If the client receives multiple configure events before it can respond to one, it only has to ack the last configure event.
A client is not required to commit immediately after sending an ack_configure request - it may even ack_configure several times before its next surface commit.
A client may send multiple ack_configure requests before committing, but only the last request sent before a commit indicates which configure event the client really is responding to.

This creates an xdg_popup object for the given xdg_surface and gives the associated wl_surface the xdg_popup role.
See the documentation of xdg_popup for more details about what an xdg_popup is and how it is used.

The window geometry of a surface is its "visible bounds" from the user's perspective. Client-side decorations often have invisible portions like drop-shadows which should be ignored for the purposes of aligning, placing and constraining windows.
The window geometry is double buffered, and will be applied at the time wl_surface.commit of the corresponding wl_surface is called.
Once the window geometry of the surface is set, it is not possible to unset it, and it will remain the same until set_window_geometry is called again, even if a new subsurface or buffer is attached.
If never set, the value is the full bounds of the surface, including any subsurfaces. This updates dynamically on every commit. This unset is meant for extremely simple clients.
The arguments are given in the surface-local coordinate space of the wl_surface associated with this xdg_surface.
The width and height must be greater than zero. Setting an invalid size will raise an error. When applied, the effective window geometry will be the set window geometry clamped to the bounding rectangle of the combined geometry of the surface of the xdg_surface and the associated subsurfaces.
