> Yes, this is indeed a fall-out of bug #7390.  As you see in
> http://debbugs.gnu.org/cgi/bugreport.cgi?bug=7390#49, the Y pixel
> issue was fixed on the trunk (in r102407), but then my temporary
> change in posn-col-row on the release branch, which shouldn't have
> been merged onto the trunk, _was_ merged (in r102428) and screwed this
> up.  Reverting that change fixed posn-col-row.
>
> As for posn-actual-col-row, the problem was in posn-at-point, which
> was returning incorrect row count when header line is present in the
> window.  I fixed that as well.
>
> Revision 117473 on the emacs-24 branch should fix both issues.
