 * XSync --
 *
 *	This routine is a stub called XSync, which is called during the Tk
 *      update command.  The language specification does not require that the
 *      update command be synchronous but many of the tests implicitly assume
 *      that it is.  It is definitely asynchronous on macOS since many idle
 *      tasks are run inside of the drawRect method of a window's contentView,
 *      which will not be called until after this function returns.
 *
 * Results:
 *	None.
 *
 * Side effects: Processes all pending idle events then calls the display
 *	method of each visible window.
