There was some original confusion in a potential loss of quality in
truetype/type2 conversions, because of quartic vs cubic spline
approximations in the two specifications.  When we were concerned that
some users may be hit by a loss-of-quality in conversion, we
considered making the conversion and subsetting optional.  Michael
later clarifed that the loss (which happens only in corner cases)
would occur in the type3->truetype conversion, and not in the
truetype->type3 case we are interested in because type3 uses quartic
and truetype uses cubic.  Unless there is a good reason to make it
optional, I would like to make it as simple as possible and simply do
the conversion and embedding every time.  This will make support and
debugging easier.
