Georgia Tobin discusses (very briefly) an aspect of font scaling in Tugboat
Vol 7, no 2. She illustrates the effect of scaling a 48 pt font to a 12
point on the ratio of ascender to descender height. Visually the ratio
appears to change, when of course it doesn't in reality. Thus, the computer
modern fonts change the ratio in the metafont input so that the ratio is
visually the same across point sizes. This also brings up why "true"
computer modern fonts cannot be converted to outlines for scaling on
postscript devices, since "true" computer modern fonts are not scaled!
