This is essentially correct with a minor correction (quibble): it is
not the X *server* that adds the decoration but the window manager.
They are two quite separate entities. The server is responsible for
handling all the protocol gunk and the window manager is basically in
charge of decoration, layout policy, iconification and
deiconification, and so forth.
It is possible, in fact, to run without a window manager at all,
although this is an extremely rare case, I'm sure. You can't,
however, in any circumstances run without an X server.
