  You're right, the technique is really only suitable to give extra
resolution on edges (e.g. for fonts) and with black and white pixels. For
font applications this is not too much of a limitation. The color fringing
you would expect can be compensated for using neighbouring pixels' energy
(this does reduce the 3X factor to some degree).
