Well, I did not try the hook, however, I think first this just adds 
default parameter, and it actually makes effect when `make-frame` is 
called, at that time client already sends server its display. Plus, GTK 
allows to set maximized before window is shown, this means the window 
will maximized once mapped, which is just what I want.

I also tried the X11 GTK version, it does not have this bug.
