562// Window constraining
563// -------------------
564//
565// To ensure that the windows are not placed under the menu bar, they
566// are typically moved by the call-back constrainFrameRect. However,
567// by overriding it, it's possible to inhibit this, leaving the window
568// in it's original position.
569//
570// It's possible to hide the menu bar. However, technically, it's only
571// possible to hide it when the application is active. To ensure that
572// this work properly, the menu bar and window constraining are
573// deferred until the application becomes active.
574//
575// Even though it's not possible to manually move a window above the
576// top of the screen, it is allowed if it's done programmatically,
577// when the menu is hidden. This allows the editable area to cover the
578// full screen height.
579//
580// Test cases
581// ----------
582//
583// Use the following extra files:
584//
585// init.el:
586// ;; Hide menu and place frame slightly above the top of the screen.
587// (setq ns-auto-hide-menu-bar t)
588// (set-frame-position (selected-frame) 0 -20)
589//
590// Test 1:
591//
592// emacs -Q -l init.el
593//
594// Result: No menu bar, and the title bar should be above the screen.
595//
596// Test 2:
597//
598// emacs -Q
599//
600// Result: Menu bar visible, frame placed immediately below the menu.
