I've seen [Win32FontInfo setupAttributes] being called when familyName is nil, which will cause a call to wcsncpy with the second argument being NULL, resulting in an AV.
This PR works around that. In this implementation, when familyNameisnil`:
logfont.lfFaceName will not be set
CreateFontIndirectW will fail
[Win32FontInfo setupAttributes] will now return NO instead of failing with an AV
