??? The `v*256' only makes sense if you read a single byte in the
loop! If you read 4 bytes in a loop, the value must be
v*256*256*256*256.

You also have to take care of the byte order in GF files if you read
more than a single byte.
Finally, it's not clear to me why you directly use
`FT_Stream_ReadULong' and not one of the many macros like
`FT_READ_ULONG' (or `FT_READ_ULONG_LE'). I strongly suggest that you
imitate code present in other font modules. Don't reinvent the
wheel...
