+
+        * xfaces.c (Vface_remapping_alist): New variable.
+        (syms_of_xfaces): Initialize it.
+        (enum named_merge_point_kind): New type.
+        (struct named_merge_point): Add `named_merge_point_kind' field.
+        (push_named_merge_point): Make cycle detection respect different
+        named-merge-point kinds.
+        (lface_from_face_name_no_resolve): Renamed from `lface_from_face_name'.
+        Remove face-name alias resolution.
+        (lface_from_face_name): New definition using
+        `lface_from_face_name_no_resolve'.
+        (get_lface_attributes_no_remap): Renamed from `get_lface_attributes'.
+        Call lface_from_face_name_no_resolve instead of lface_from_face_name.
+        (get_lface_attributes): New definition that layers face-remapping on
+        top of get_lface_attributes_no_remap.  New arg `named_merge_points'.
+        (lookup_basic_face): New function.
+        (lookup_derived_face): Pass new last arg to `get_lface_attributes'.
+        (realize_named_face): Call `get_lface_attributes_no_remap' instead of
+        `get_lface_attributes'.
+        (face_at_buffer_position): Use `lookup_basic_face' to lookup
+        DEFAULT_FACE_ID if necessary.  When optimizing the default-face case,
+        return default_face's face-id instead of the constant DEFAULT_FACE_ID.
+
+        * xdisp.c (init_iterator): Pass base_face_id through
+        `lookup_basic_face' when we actually use it as a face-id.
+        (handle_single_display_prop): Use `lookup_basic_face' to lookup
+        DEFAULT_FACE_ID.
+
+        * fontset.c (Finternal_char_font): Use `lookup_basic_face' to
+        lookup the initial face-id.
+
+        * dispextern.h (lookup_basic_face, Vface_remapping_alist): New decls.
