Set the autohint value to true:

        $ xfd -fa serif:autohint=true

Applications can set the FC_AUTOHINT boolean to FcTrue.

Xft's LCD mode hasn't changed, so non-integer stem widths will still look 
horrible.  It might be nice to have an option that made the auto-hinter 
bail on shape consistency and keep stems snapped to integer pixels like 
the instructed TT hinter usually does.  Is it possible for the autohinter 
to adjust diagonal and curved elements of the glyph to match the snapped 
stems?
