the most prominent change was the way pdftex handles tfm of fonts found
in included pdf's. Thanks to Harmut's work on using the avl library,
things are much cleaner now.

if auto expansion is not used, then pdftex behaviour doesn't change. The
only thing that is gone is the font expansion factor, which proved to
cause a lot of troubles and didn't bring any benefit. My intention was
to use this parameter to simulate font expansion by letterspacing. 

In short, auto font expansion is just like `normal' font expansion,
except that a few things are done automatically ;)
