I was under the impression that the "hints" allow the font machinery
to do adjustments based on target point size.  From my experiments, linear
font scaling doesn't look that great.

Psroff 3.0 has a HP Laserjet bitmap font scaling program.  It's strictly
linear.  When you scale up, the stroke relative widths stay constant.  But
what started being a reasonable Roman font starts looking bold, and bold starts
looking very fat.  (this is with relatively large magnifications.  Eg:
10pt -> 36pt)  Quite useable within my range of sizes, but still noticable.
