I believe that changing the root FT_Size metrics when the auto-hinter is called
is not a viable option, since the same object could be re-used later for
native hinting (TrueType or Postscript), this runs the risk of altering the
results in random ways in various rare circumstances.

(that's why the recent changes to the native TrueType driver do not store
 the re-computed metrics in the root metrics anymore but in a private
 area)

I thus can't accept your patch directly. I thought that the changes I'd made
to the auto-hinter did indeed work. I'll try to check if this is really
true, and how to fix it cleanly.
