   When an area of the display is modified or refreshed, your callback

   refreshed areas, and a list of the refreshed rectangles. The rectangles
   are in global coordinates.

   To register a screen refresh callback function, call the function
   `CGRegisterScreenRefreshCallback'. Quartz invokes your callback function
   when operations such as drawing, window movement, scrolling, or display
   reconfiguration occur on local displays. When you are finished using a
   callback registration, call `CGUnregisterScreenRefreshCallback' to remove
   it.

   Note that a single rectangle may occupy multiple displays, either by
   overlapping the displays or by residing on coincident displays when
   mirroring is active. You can use the function `CGGetDisplaysWithRect' to
   determine the displays a rectangle occupies. }

{ Return a Core Foundation mach port (CFMachPort) that corresponds to the

   Use this function to detect if the window server process exits or is not
   running. If this function returns NULL, the window server is not running.
   This code example shows how to register a callback function to detect
   when the window server exits:

     static void handleWindowServerDeath(CFMachPortRef port, void *info) (
       printf("Window Server port death detected!\n");

     )

   Note that when the window server exits, there may be a few seconds during
   which no window server is running. This function will return NULL until a
   new window server is running.

   Your program will need to run a CFRunLoop for the port death callback to
   function. A program which does not use a CFRunLoop may periodically call
   `CFMachPortIsValid' to check whether the port is valid. }
