There is not a single font driver in FreeType that uses `FT_FILE'.
It's definitely the wrong interface. FreeType either accepts font
files or fonts that are preloaded into a memory buffer. For the
latter you can't use `fopen' and friends; this is another reason for
being the wrong interface.
Function `gf_load_font' gets an `FT_Stream' object; this means you can
use the FT_STREAM_XXX macros, for example `FT_STREAM_SEEK'.
I suggest that you have a look (again :-) into `winfnt.c'.
