Seems a little bit too complex. ;-)
And doing this would need to be done for the other versions of zlib...

There are more important things to look at IMO. The encoding stuff and the
various functions to get the sizes, kerning information, etc. don't work
with the ttu-font-metrics. In a second time it would probably be a good idea
to try to optimize somewhat the in-memory representation of the font data.
(If it is possible of course.) I will look at that.

Good to know.
