That's irrelevant: `fontification-functions' uses 1 text property
(`fontified') to determine what's been fontified.  Whether the
"fontification" itself uses text-properties or overlays or bananas
doesn't matter as long as it's behavior is consistent with the behavior
of the `fontified' text property.  `glasses-mode' has been using
jit-lock together with overlays just fine.
