* TkMacOSXFlushWindows --
*
* This routine is a stub called by 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 assume that is the
* case. It is not naturally the case on macOS since many idle tasks are
* run inside of the drawRect method of a window's contentView, and that
* method will not be called until after this function returns. To make
* the tests work, we attempt to force this to be synchronous by waiting
* until drawRect has been called for each window. The mechanism we use
* for this is to have drawRect post an ApplicationDefined NSEvent on the
* AppKit event queue when it finishes drawing, and wait for it here.
*
* Results:
* None.
*
* Side effects:
* Calls the drawRect method of the contentView of each visible
* window.
