There ends up being 2 ways that a IDWriteFont is created, one via 
existing data (as shown here) where we do not need the data initialized 
and one via an external resource (Such as a logfont or IDWriteFontFace) 
where we will use the initialized data.

Would you prefer that I do not alloc/initialize the data in create_font 
and instead only alloc/initialize in the external resource case?

thanks!
