Is this really true ? I thought that Italics were a very old idea,
and were basically a curvy character different from the ``original''
face, while oblique was less than 100 year old, and was just slanted
versions of the ``original'' face. I never saw any reference to
serif vs. sans-serif fonts. Another thing to perhaps back this
up is that Times-Roman oblique != Times-Italics.

Yes, I agree.  That's the very point I was making badly.  Italic is not
just slanting, i.e. you don't get Times-Italic by putting Times-Roman
through a skewing matrix.  Italics are a different design within the
family.  In careless nomenclature, all sloping fonts, italic or not,
get called italic.

Looking through my list of AFM filenames I see LucidaSans-Italic and
StonsSans-Italic. So, with some exceptions, sans serif fonts have just
the oblique variation, while serif fonts can have italic and slanted
variations, e.g.  Computer Modern Slanted and Computer Modern Italic.
(Besides the Bold/Light axis of course, in case you were going to point
that out.)

Being too terse in postings has drawbacks too.
