[cairo] cairo on win64

Yes. I have built cairo for 64-bit Windows and yes, it seems to work
fine. Some patches were needed to pixman to avoid warnings (dunno if
the code might still have worked) because of assumptions that
sizeof(unsigned long) == sizeof(void*). See
https://bugs.freedesktop.org/show_bug.cgi?id=17789 . For cairo no
changes to the sources were needed.

Prebuilt binaries for Win32 (with just Win32 font support) at
http://ftp.gnome.org/pub/GNOME/binaries/win64/dependencies/ , but of
course, depending on what you intend to do with cairo, you might want
to compile it yourself instead.
