* GdipCreateFont [GDIPLUS.@]
*
* Create a new font based off of a FontFamily

* *fontFamily [I] Family to base the font off of
* emSize [I] Size of the font
* style [I] Bitwise OR of FontStyle enumeration
* unit [I] Unit emSize is measured in
* **font [I] the resulting Font object
*
* RETURNS
* SUCCESS: Ok
* FAILURE: InvalidParameter if fontfamily or font is NULL.
* FAILURE: FontFamilyNotFound if an invalid FontFamily is given
*
* NOTES
* UnitDisplay is unsupported.
* emSize is stored separately from lfHeight, to hold the fraction.
