Make Helvum more accessible for assistive technologies such as screen readers.
Helvum should work for people using screen readers and other accessibility tools.
Right now, almost nothing is readable using a screen reader.
- Make sure the flatpak can access the accessibility bus
- Implement
Gtk.Accessible
as needed - Ensure a Screen Reader can at least walk through the graph and read node names and port names
- Try exposing the media type in some convenient way.
- Try making links accessible for screen readers.
GTK_ACCESSIBLE_RELATION_FLOW_TO
might be used to indicate linked ports and let the user jump to them.
