What kerning? :P Anyway, I plotted this with a 4mil pen, the small text is only 30mil IIRC... BTW these are package names and RS order numbers so evenif they're not readable in the plot who cares :D

Maybe the 'kerning' error you talk about is due to integer roundup... this issue was already discussed about the partial zoom, IIRC.

Thank you :P the overbarring is already in SVN from some time, BTW...

The Hershey collection has glyphs for latin, cyrillic and technical greek (in the 'symbols'). Extended accents could be done with composition (GNU plotutils does so to implement Latin-1... btw it contains the full repository,including kana and kanjis).

The problem is I don't think Cairo can do XOR. And, anyway, we need a vector font for doing gerbers...
