[Debarshi Ray <debarshir src gnome org>]

commit 826a29e4ae1193fdfd26ebfc3e614681895c914f
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
