    libdocument: Load application-specific gdk-pixbuf loaders
    
    Use a new gdk-pixbuf feature to integrate application-provided
    gdk-pixbuf loaders.
    
    This makes it easy to include non-standard loaders without touching the
    system installation.
    
    See https://gitlab.gnome.org/GNOME/gdk-pixbuf/merge_requests/34
