// 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)

unaltered. When a parent frame is iconified or made invisible, its
child frames are made invisible. When a parent frame is deleted,
its child frames are deleted too.

/* An IOSurface is a pixel buffer that is efficiently copied to VRAM
for display. In order to use an IOSurface we must first lock it,
write to it, then unlock it. At this point it is transferred to
VRAM and if we modify it during this transfer we may see corruption
of the output. To avoid this problem we can check if the surface
is "in use", and if it is then avoid using it. Unfortunately to
avoid writing to a surface that's in use, but still maintain the
ability to draw to the screen at any time, we need to keep a cache
of multiple surfaces that we can use at will.
The EmacsLayer class maintains this cache of surfaces, and
handles the conversion to a CGGraphicsContext that AppKit can use
to draw on.
The cache is simple: if a free surface is found it is removed from
the cache and set as the "current" surface. Emacs draws to the
surface and when the layer wants to update the screen we set it's
contents to the surface and then add it back on to the end of the
cache. If no free surfaces are found in the cache then a new one
is created. */
