OK.  So what other function(s) can be used for this purpose?

If there are no good alternatives, I guess we will go with
GetCharABCWidthsFloatW anyway, since the situation cannot become worse
than it is already.

Btw, I used your recipe, but didn't see any significant slowdown with
fixed.fon (also, the file bigline.txt is missing, I just used the
16384 thingy instead.
