       mitem_visible - check visibility of a menu item
       #include <menu.h>
       bool item_visible(const ITEM *item);
       A  menu  item  is  visible  when it is in the portion of a
       posted menu that is mapped onto the screen (if the menu is
       scrollable,  in  particular,  this portion will be smaller
       than the whole menu).
       curses(3x), menu(3x).
       The header file <menu.h> automatically includes the header
       file <curses.h>.
       These  routines  emulate  the System V menu library.  They
       were not supported on Version 7 or BSD versions.
