commit 20fc2d1d0f3359b5738a2cc685f304a18e116be8
Author: Evan Welsh <contact evanwelsh com>
Date: Tue Dec 28 06:40:37 2021 -0800
Implement GObject.registerType API
GObject.registerType is a complementary API to
GObject.registerClass which is compatible with
new class features like class fields.
GObject.registerType does not replace the
original constructor, instead it stores the
GObject prototype separately.
Fixes #331
