The maximum size of a window is defined by the values placed in the
wMaxH and wMaxW fields of the NewWindow parameter block.  Most programs
with resizable windows set the maximum size of their windows to
approximately the size of the screen - they do not expect that their
windows will be moved off the screen.  A program written with an expanded
desktop in mind, though, could set its windows' maximum width and height to
large values and let users create huge windows which can be manipulated
with JumboDesk.  The Finder, for example, permits the creation of windows
which are a bit higher than the screen, so JD could be used to create
and view a window which would not fit on a single screen.
