    view: add internal-children "left_gutter" and "right_gutter"
    
    TODO:
    - in a .ui file, be able to add renderers in a Gutter object (the
    position needs to be specified). And with an id="my_renderer", it should
    be possible to use
    gtk_widget_class_bind_template_child_internal_private() to access the
    renderer in the code.
