Hi Werner, this is a PostScript font, not a TrueType, and as usual it 
depends on using Ghostscript as the FreeType client, so I can't easily do 
this. The problem is that all the matrix transforms and so on are created 
to fit the GS requirements, it would be difficult if not impossible to 
recreate these rather exacting conditions elsewhere.

However, I did notice while reading ftraster.c that it can be built 
stand-alone without the rest of FreeType (I hope that's not just a legacy 
comment ;-)

So what I plan to do is create a *very* simple test harness that feeds in 
the problematic numbers, and debug my way through the code. Assuming that 
works, would that be OK to pass along to you ? I should probably open an 
issue at Savannah if I do that I guess.
