 638 // possible to hide it when the application is active. To ensure that
 639 // this work properly, the menu bar and window constraining are
 640 // deferred until the application becomes active.
 641 //
 642 // Even though it's not possible to manually move a window above the
 643 // top of the screen, it is allowed if it's done programmatically,
 644 // when the menu is hidden. This allows the editable area to cover the
 645 // full screen height.
 646 //
 647 // Test cases
 648 // ----------
 649 //

 651 //
 652 //    init.el:
 653 //       ;; Hide menu and place frame slightly above the top of the screen.
 654 //       (setq ns-auto-hide-menu-bar t)
 655 //       (set-frame-position (selected-frame) 0 -20)

 657 // Test 1:
 658 //
 659 //    emacs -Q -l init.el
 660 //
 661 //    Result: No menu bar, and the title bar should be above the screen.
 662 //
 663 // Test 2:
