;; I started a new emacs and ran (setq frame (make-frame '((tool-bar-lines
. 0))) ).  Then I set the
;; fullscreen parameter with results indicated below.

(set-frame-parameter  frame  'fullscreen  'maximized)
;; The outersize changed to fullscreen, the (real) workarea did not change
in size, but it did
;; relocate to Left Top.  In other words the result was very similar to a
normal, problem, start.

(set-frame-parameter  frame  'fullscreen  'fullboth)
;; From the position above, this caused the outerframe to increase in
size, eliminating the frame
;; border.  The workarea moved, further Left Top, but did not change in
size.

(set-frame-parameter  frame  'fullscreen  'fullheight)
(set-frame-parameter  frame  'fullscreen  'fullwidth)
;; I have never used these, so I do not know how they are intended to
work.  After these, the shape
;; changed to fullheight and fullwidth, respectively.  The other dimension
changed to the width and
;; height of the workarea and the whole outershape moved so that it was
centered horizontally and
;; vertically respectively.  The attached screenshot shows one of these
configurations.
