Existing Type 1 fonts don't have any such "real size" optimizations.  The
tuning which is done is performed by the raster-conversion algorithms in
the interpreter--but this is tuning for a particular device (and its par-
ticular resolution and rendering characteristics), not for effects related
to human perception and/or esthetics.
