I am very surprised by this, since ATM, for example, completely ignores the
UniqueID.  PS printers use it to manage their glyph cache, and can give
very strange results when bogus UniqueIDs are used.  As far as I know,
both ATM and Acrobat manage their caches based on PS FontNames.
Which is why output from DVIPS is a problem, since it uses the original
PS FontName with modified fonts (e.g. subsetted fonts).
