+ <description summary="Server side window decoration manager">
+ This interface allows to coordinate whether the server should create
+ a server-side window decoration around a wl_surface representing a
+ shell surface (wl_shell_surface or similar). By announcing support
+ for this interface the server indicates that it supports server
+ side decorations.
+ </description>
+ <request name="create">
+ <description summary="Create a server-side decoration object for a given surface">
+ When a client creates a server-side decoration object it indicates
+ that it supports the protocol. The client is supposed to tell the
+ server whether it wants server-side decorations or will provide
+ client-side decorations.
+
+ If the client does not create a server-side decoration object for
+ a surface the server interprets this as lack of support for this
+ protocol and considers it as client-side decorated. Nevertheless a
+ client-side decorated surface should use this protocol to indicate
+ to the server that it does not want a server-side deco.

+ This event is emitted directly after the decoration is created and
+ represents the base decoration policy by the server. E.g. a server
+ which wants all surfaces to be client-side decorated will send Client,
+ a server which wants server-side decoration will send Server.
+
+ The client can request a different mode through the decoration request.
+ The server will acknowledge this by another event with the same mode. So
+ even if a server prefers server-side decoration it's possible to force a
+ client-side decoration.
+
+ The server may emit this event at any time. In this case the client can
+ again request a different mode. It's the responsibility of the server to
+ prevent a feedback loop.
