gtk/gdk/wayland/gdkscreen-wayland.c
Lucas Baudin 306ee6d9a5 wayland: recursively search for the settings schema. 
On some systems, the gtk settings are not used properly for wayland.
Indeed, g_settings_schema_source_get_default is used, and as the docs says it,
"all lookups performed against the default source should probably be done
recursively.".
