Oops, I realize now where I went wrong which led to me saying that linear
scaling doesn't work that well.  My code scales *bitmaps* (not outlines),
and given the that the base fonts are fairly small pointsizes (10),
they've been "hinted" already.  Ie: linearly scaling a hinted bitmap may not
look all that great.
