I spent a fair amount of time in April thinking about the
font mapping problem for support of foreign fonts, such as
PostScript fonts, in my DVI drivers.  I concluded that the
composite font mechanism proposed by Don Knuth does indeed
solve the problems in a general way, and I therefore
conclude that mappings should NOT be in macro packages.

[I think TeX should have originally supported a mapping
array for each font; that mapping could have been set when a
font was loaded.  However, it is not obvious that mapping
implemented at the macro level would be sufficiently
efficient.]
