- 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.
