There is quite a bit of send client events, get properties and stuff going on,
but it is according to the Extended Window Manager Hints Specification.  I
have seen that it is very slow when running on a remote display over a not so
fast connection.  When I run locally it is very fast (maybe 0.1 second).

We could implement some sort of caching of the query where we find out what
the window manager supports.  But I think that is something for after the
release, and the initial fullscreen would then be as slow as before anyway.

That was a bug,
(set-frame-parameter nil 'fullscreen nil)

should work now.  The "unresizable" property is a thing your window manager
