Fix minor default in Fl_Window::wait_for_expose() under Mac OS.

Browse Source 
If the exposed window contains a sub-window the sub-window can disappear
after having been drawn. This can be seen with the device demo
completed with a wait_for_expose() call just after the main window show().
The fix applies wait_for_expose() recursively for all subwindows.
