fdo#55931 Fix renderding of subscript/superscript with Autofit Text.

We are using font metrics to compute the stretch ratio for autofit; but that
collides with nPropr property of SvxFont - it is then counted twice, ie. in
the case of nPropr == 25, we actually behave as if it was much less; and
worse, only in the horizontal direction.
