Arial Black has a wrong descender, it should have been negative. In the next release
I'll add a fix to flip the sign if the descender is positive. If you want to try the
fix in TrueTypeFont, replace:
os_2.sTypoDescender = rf.readShort();
with
os_2.sTypoDescender = rf.readShort();
if (os_2.sTypoDescender > 0)
os_2.sTypoDescender = (short)(-os_2.sTypoDescender);

> Any ideas? Could the Basefont-class have any problems??
> Hope a solution can be found.
