MetaGravity is an enum, where the values match the X11 macros used for gravity, with the exception that `ForgetGravity` was renamed `META_GRAVITY_NONE` to have less of a obscure name. The motivation for this is to rely less on libX11 data types and macros in generic code. https://gitlab.gnome.org/GNOME/mutter/merge_requests/705
