Thanks for writing. I too reported a problem with cairo-generated  
PDFs which looked fine in Adobe Reader but not OS X Preview. I'm not  
sure if your case is the same as the one I was seeing. My problem was  
that my PDFs are generated by graphviz, and I was unsure if the  
problem was in cairo, graphviz, or Mac OS X's PDF renderer. Your  
message gives me hope that it might be a cairo problem after all.

Unfortunately we didn't get very far in trying to solve the problem I  
reported:

I did get far enough to see that it looks like Preview *is* rendering  
the missing curves, just not at the desired offset:

Note that the glyph difficulties reported in the latter mail have  
already been resolved in the current version of cairo; only the curve  
offset problem remains for me.
