GEPS 029: GTK3-GObject introspection Conversion
Gramps was written with GTK 2 toolkit. This has been replaced upstream with GTK 3, so Gramps should convert to GTK 3.
We try to convert 1 to 1. If there are problems due to deprecated features, or otherwise, add in the code:
# TODO GTK3: write what problem is due to gtk 3 conversion
Before release, all TODO GTK3 in the code must be cleaned up
Python GTK3 docs: 
Alternative is to look at the base C documentation, and understand from experience how the introspection works. Gnome docs: .
As python works with classes, it looks somewhat like the C++ interface: . To investigate the specific override (how to init Gtk classes):

Furthermore, for the other gi libs:
- glade can no longer work with our catalog. We need to upgrade comboboxentry to combobox with has_entry manually, and hope editors keep working...
- expose is no longer present on gtk.widget. Draw must be used. Unclear how, .
- Gtk.Clipboard seems to work differently
