Protocols related to window management
The way for a client to pass focus to another toplevel is as follows.
This interface allows a compositor to announce support for server-side decorations. A window decoration is a set of window controls as deemed appropriate by the party managing them, such as user interface components used to move, resize and change a window’s state. A client can use this protocol to request being decorated by a supporting compositor. If compositor and client do not negotiate the use of a server-side decoration using this protocol, clients continue to self-decorate as they see fit.
