Metafont/Fontforge problems (Issue 3772)

[Marc Hohl]

Hi list,

it seems that there are some incopatibilities with my current
setup (Ubuntu 12.04, fontforge 20110222) and the environment
where Patchy runs.

http://code.google.com/p/lilypond/issues/detail?id=3772#c22

shows the current mangled output, but my machine at home
compiles the file clefs.ly without the artifacts.

As I cannot reproduce the error, I can't continue to work on this patch,
son any help/hints are highly apprechiated!

Thanks,

Marc
