+  Most faces don't have an explicit setting of the @code{:height}
+attribute, and thus inherit the height from the @code{default} face.
+Those faces are also scaled by the above commands.
+
+  Faces other than @code{default} that have an explicit setting of the
+@code{:height} attribute are not affected by these font size changes.
+The @code{header-line} face is an exception: it will be scaled even if
+it has an explicit setting of the @code{:height} attribute.
