;;; Face attributes.
-;; Below, nil is used in widget specifications for `unspecified' face
-;; attributes and `off' is used instead of nil attribute values. The
-;; reason for this is that nil corresponds to the result you get when
-;; looking up an attribute in a defface spec that isn't contained in
-;; the spec.
