Add a "gboolean edge_lock" parameter to GimpChannel::feather() and a
"Selected areas continue outside the image" toggle to the "Feather
Selection" dialog, just like they exist for shrink selection and
border selection. At the end, convert the boolean to the right abyss
policy for gegl:gaussian-blur.
