GDI and Uniscribe have a close relationship, but GDI+ and Uniscribe do not.
They have a shared heritage cbut entirely separate shaping engines and logic
(even in cases where they originally came from the same source) -- one is
*not* a wrapper around the other.
I only mention this because you seem to be implying otherwise in your posts.
