Correct me if I'm wrong, but this is *not* what the hints do, and is indeed
one of the drawbacks of Postscript. What the "hints" do is adjust for low
resolution (300 dpi) printers. Otherwise the letters tend to look "heavy."
On a high-resolution printer like a Linotronic, however, fonts are scaled
exactly, that is a 48 point 'A' looks exactly like a 24 point 'A' except it's
larger. This is also Adobe's Expert Collections contain what are called
"Titling" characters, i.e. fonts designed for larger point sizes.

One of the advantages of TrueType when it finally appears is that
it will incorporate the "nonlinear scaling" that Mr. Rosen describes.
