FT_New_Memory_Face approach need to change the AddFontFileToList,
OpenFontFile function. this change makes the complicated code, but
"memory font resource" only need for Add/RemoveFontMemResourceEx api.
I think temp file approach is simple solution.

#34 patch code of BUG#5865 already use the FT_New_Memory_Face approach.
please see the #34 patch code.

PS. #34 code must fix. RemoveFontMemResourceEx of #34 patch code has the
critical problem.
