- Set the "gimp30-python" Gettext domain and bind it to the proper
locale directory as installed by GIMP.
- Localize various strings with gettext.
- Remove calls to self.set_translation_domain() in
do_query_procedures(). This is technically wrong right now but I am
going to get rid of the menu item localization for plug-ins done by
the core.
Since meson 0.43.0 (below our current requirement), 'symbol_prefix'
argument of gnome.generate_gir() allows an ordered list. If I prepend
'gimp_ui', it makes any gimp_ui_*() function to not start with 'ui_'.
In particular, GimpUi.ui_init() becomes GimpUi.init() which is much less
redundant.
Since the patch was initially contributed, some parts of the
introspection changed. First all GUI-related code is in a GimpUi module
now.
Also Gimp.get_pdb().run_procedure() is now using a list instead of a
GimpValueArray.
