This is what I was discussing with you previously, that this should be removed
as it is the only place where the typeface should have a back pointer to whence
it came (which it may not even have). This was introduced just for FontHost,
which was the only user. This CL changes FontHost to just use the equivalent
method on the default FontMgr.
