Some of the marshallers we generate in `clutter-marshal.list` are also available in GLib, so we don't need to generate them ourselves. Even more, by passing NULL to `g_signal_new` in these cases will actually internally optimize this even more by also setting the valist marshaller, which is a little bit faster than the regular marshalling using `GValue` and libffi. https://gitlab.gnome.org/GNOME/mutter/merge_requests/700
