Subject: macOS: creation of window with subwindow in iconized form -
 continued.

With macOS 10.13 and 10.14 at least, recursivelySendToSubwindows:@selector(display)
is not necessary in the new procedure where the window icon is computed in
windowDidMiniaturize rather than in windowWillMiniaturize as was done before.
