[cairo] freetype on windows

[Kozhevnikov Mikhail]

Hi,

I've got a bug report for Dingo on Windows having some fonts displayed incorrectly. It appears to be again the same one mentioned here http://lists.cairographics.org/archives/cairo/2009-October/018321.html. 
I thought of using Freetype font backend to fix this. However, there's a problem as Dingo is built with MSVC, while fontconfig.h requires unistd.h.

Has anyone tried using freetype on Windows with MSVC?

Cheers, 
Mikhail.
