+The first four functions get and set those windows.
+It is not necessary to set
either window; by default, the driver code uses \fBstdscr\fR for both.

In the \fBset_\fR functions, window argument of \fBNULL\fR is treated as though
it were \fBstsdcr\fR. A menu argument of \fBNULL\fR is treated as a request
to change the system default menu window or subwindow.

The function \fBscale_menu\fR returns the minimum size required for the
subwindow of \fImenu\fR.
