Answer: There is no explicit support for this.  Maximizing makes sense in
single tasking operating systems where the user must choose one application to
be active.  Motif usually runs in multi-tasking operating systems where
several applications may be active and having one take over the screen is
undesirable.

If you must make your application full screen, use the Xlib macros to compute
the root window size and set the width and height of your shell to this size.
You may want to leave a little space around the edges for the window manager
frame.
