Hmm.  I need to go back through the opentype archives (from June-December of
1998) to see if that's where I got the original info.  Most of the SBIT
correspondence I still have is from December 1998, but none of it references
the SIZE extension.

It might have come from David Meltzer at Microsoft (who helped me with some
other SBIT questions), but I'm not sure about that.

I do recall locating something about the SIZE extension somewhere on the web
at the time I added support to xmbdfed, but searching the past couple days
hasn't turned up anything.
