 MIN_REQUIRED signals that programs are expected to run on at least GLib 2.32/GTK+ 3.4 and thus deprectation warnings for newer versions (such as gtk_scrolled_window_add_with_viewport() being deprecated in GTK+ 3.8) should be suppressed.
 MAX_ALLOWED signals that programs will not use features introduced in newer versions of GLib/GTK+ and that the compiler should warn us if we slip.
