I used the following to get a full-screen window.  Note that the menu
bar is not affected.

Setup.  Done once.

	SetRect(&window_bounds, 0, 0,
	    screenBits.bounds.right - screenBits.bounds.left,
	    screenBits.bounds.bottom - screenBits.bounds.top
	);
	window = NewWindow(NIL, &window_bounds, "\p", false, plainDbox, ...);

To display the window (effected by a dialog option):

	SelectWindow(window);
	ShowWindow(window);
	/*
	 * This is needed to get a full-screen window.
	 * It effectively hides the menu bar.  It must
	 * be after ShowWindow().
	 */
	CopyRgn(window->clipRgn, window->visRgn);
	SetPort(window);
	InvalRect(&thePort->portRect);

The update event causes the actual window contents to be drawn.

Note: this is very fragile: the menu bar pops up if you put up a
desk accessory or similar.  Also, SuperClock overwrites the display.

I'm using it for a display application on a dedicated Mac (reads data
from the network and shows it on a display screen).  I've used this on
a non-networked application where the window is displayed after exiting
a dialog.  The main event loop hides the window after a mouse click.
(Yes, I know this violates the guidelines.)
