Indeed.  You're right on point.  I simplified things a bit though.  The
matcher should first try to match a font that has the desired (point, not
pixel) size in its supported range, and failing that, pick the one with
closest design size.

It's really perhaps 200 lines of code, and mostly in getting the 'size'
parameters out of the font.
