I had a patch that introduced a "max-fuzz" variable such that any font whose
size is too far apart (by default the acceptable fuzz was 12.5%) from the
target size is rejected.

The original reason for introducing it was to give preference to unscaled
bitmap fonts while still reverting to a scaled font (potentially auto-scaled
from a bitmap) if the requested size was not close to any of the bitmap
fonts available.

I can't find the patch any more, tho.  Hopefully, anti-aliasing will make
bitmap fonts obsolete soon enough.
