Desktop environments may extend this enum by taking up a range of

A client should arrange a new surface, and then send a

The window geometry of a window is its "visible bounds" from the

portions like drop-shadows which should be ignored for the
purposes of aligning, placing and constraining windows.
The default value is the full bounds of the surface, including any
subsurfaces. Once the window geometry of the surface is set once,
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 responding to a configure event, the window geometry in here
must respect the sizing negotiations specified by the states in
the configure event.

An interface that may be implemented by a wl_surface, for

surface is a transient surface with an added pointer grab.
An existing implicit grab will be changed to owner-events mode,
and the popup grab will continue after the implicit grab ends

unmapped).
The popup grab continues until the window is destroyed or a mouse
button is pressed in any other clients window. A click in any of
the clients surfaces is reported as normal, however, clicks in
other clients surfaces will be discarded and trigger the callback.
The x and y arguments specify the locations of the upper left

parent surface, in surface local coordinates.
xdg_popup surfaces are always transient for another surface.
