NAME
        ZipWindow -- Change window to "alternate" position and
                     dimensions. (V36)

    SYNOPSIS
        ZipWindow( window )
                   A0

        VOID ZipWindow( struct window * );

    FUNCTION
        Changes the position and dimension of a window to the values
        at the last occasion of ZipWindow being called (or invoked
        via the "zoom" gadget).

        Typically this is used to snap between a normal, large, working
        dimension of the window to a smaller, more innocuous position
        and dimension.

        Like movewindow(), sizewindow(), and changewindowbox(), the action of
        this function is deferred to the Intuition input handler.

        More tuning needs to be done to establish initial values for
        the first invocation of this function for a window.  You can
        provide initial values using the openwindow() tag item
        WA_Zoom.

        It could also use a new name, but "ZoomWindow" is misleading,
        since "Zoom" normally implies "scale."

        The zoom gadget will appear (in the place of the old "toback"
        gadget) when you open your window if you either specify a
        sizing gadget or use WA_Zoom.

        You can detect that this function has taken effect by receiving
        an IDCMP_CHANGEWINDOW IDCMP message.

    INPUTS
        window -- window to be changed.

    RESULT
        None

    BUGS
        openwindow() assumes that the proper default "other" dimensions
        are "full size."
