I think we are getting slightly different things with the Windows/Mac
vs. UNIX solutions (at least as of David's current MaxWindowSize
routine): Mac is returning the size of the available space to put a
window (the full size of a maximally sized window including the menubar)
and UNIX is returning the size of the graphics part of a maximally sized
window.

So the following isn't true for Macs (I don't know about Windows):

; To create a window of maximum size::
; maxsize = MaxWindowSize()
; Window, XSize=maxsize[0], YSize=maxsize[1], /Free

This creates a window that you can't see the bottom of because the
menubar of the graphics window is "pushing" the window down a bit extra
(remember there are two menubars when dealing with an X window on Mac OS
X: the normal Mac menubar that is always there *and* a Windows-like
menubar on each window).

If you want to create a maximally sized graphics window so that the
above example code works, then on Mac I think it has to use the UNIX
solution. Does this work on Windows? IDLsysMonitor::getRectangles with
EXCLUDE_TASKBAR excludes the windows menubar too?
