Good to know! I've asked this question repeatedly but I never got an
answer. Will add a proper remark to the sources.

Your screenshot shows that there's something fishy with FreeType'2 TT
code. If you call `ftview -r 96 8 tahoma.ttf' (from the current CVS,
with bytecode interpreter and patented hinting enabled) you can see
that both the glyphs `6' and `8' have one pixel too much. Either
there's a bug in the bytecode interpreter, or there is a problem with
the dropout code in the renderer.
Since tahoma is probably one of the most used fonts I ask you to
invest some time to find the problem.
