Subject: - Implement Fl_Window::wait_for_expose() for Mac OS: The -[NSWindow
 makeKeyAndOrderFront:] message used to make the window appear on the screen,
 but, starting with 10.10 (approximately), this changed, and it became
 necessary to query for events for a new window to appear on the screen. With
 10.11 two event messages are needed. The solution is therefore to implement
 Fl_Window::wait_for_expose().

- Calling NSDisableScreenUpdates()()/NSEnableScreenUpdates() before and after window updates
greatly accelerates multi-window update operations.
