Summary: UniqueID in subsetted Type1 fonts

Initial Comment:
The currant version of pdftex removes the UniqueID from
the font dictionary when a subset of a Type1 font is
included.  However, there is still a UniqueID in the
Private dictionary which should be removed too.

>From the PostScript Language Reference Manual (p. 336):

> When you copy a font dictionary for the purpose of 
> creating a modified font, you should not copy the 
> UniqueID or XUID entry. As an exception to this 
> general rule, it is acceptable (and preferable) to 
> retain the original UniqueID or XUID entry if
> the only modified entries are FontName, FontInfo, 
> FontMatrix, or Encoding, because those changes do not
> affect the glyphs’ appearance or metrics.

Regards,
  Reinhard
