It might be related, though it's not certain. I can't tell, really.

No, you don't need to multiply by 65535. the values in ttface->bbox are 
already in
outline coordinates, you simply output them as integers into the 
Postscript/Type1 stream.

this is consistent with PSType3_createOutlineGlyphs which also outputs 
glyph points
in outline coordinates.

Oh, I'm not dissing anyone, believe me. I'm just finding some irony 
between the efforts involved
and the end result. that's all, nothing more.

And believe me, I would have called him a moron if that's what I thought 
(which I don't)
