// Window constraining
// -------------------
//
// To ensure that the windows are not placed under the menu bar, they
// are typically moved by the call-back constrainFrameRect. However,
// by overriding it, it's possible to inhibit this, leaving the window
// in it's original position.
//
// It's possible to hide the menu bar. However, technically, it's only
// possible to hide it when the application is active. To ensure that
// this work properly, the menu bar and window constraining are
// deferred until the application becomes active.
//
// Even though it's not possible to manually move a window above the
// top of the screen, it is allowed if it's done programmatically,
// when the menu is hidden. This allows the editable area to cover the
// full screen height.
//
// Test cases
// ----------
//
// Use the following extra files:
//
//    init.el:
//       ;; Hide menu and place frame slightly above the top of the screen.
//       (setq ns-auto-hide-menu-bar t)
//       (set-frame-position (selected-frame) 0 -20)
//
// Test 1:
//
//    emacs -Q -l init.el
//
//    Result: No menu bar, and the title bar should be above the screen.
//
// Test 2:
//
//    emacs -Q
//
//    Result: Menu bar visible, frame placed immediately below the menu.
