[Emmanuele Bassi <ebassi src gnome org>]

commit 0725f1c3f1a10b514b075f7da46165389feb8f6d
Author: Emmanuele Bassi <ebassi gnome org>
Date:   Tue May 19 16:14:40 2020 +0100

    Remove gegl_operation_meta_watch_node() and friends
    
    Gegl 0.4.23 removed these symbols: properties are automatically
    monitored and forwarded through g_object_bind_property().
    
    Fixes: #149
