Oops, no. That's wrong in 16256 cases, roughly 24.8%. Should have checked
before I spoke. My deepest apologies.

Guess downconverting has to be slow, unless you know you've taken Frank's
not quite precise shortcut when upconverting. (Well, if you feel the need
for speed you could always sacrifice 65536 bytes to a lookup table.)
