[Freetype] A question so stupid . . .

[Ian Pilcher]

. . . that no one seems to have ever asked it before!

I'm trying to interpret some of the information in the PostScript table,
specifically the italicAngle member.  I'm trying to convert the 16.16
"fixed float" to a C double, and I can't get my results to match those
produced by any of the TrueType->PostScript conversion utilities out
there.  Of course, I don't really know that these utilities are doing
it right, so could someone take a look at the following and tell me if
I'm doing anything wrong?

inline double Double_From_TT_Fixed(TT_Fixed fixed)
{
    short           mantissa;
    unsigned short  fraction;
    double          result;

    mantissa = (short) ((fixed & 0xffff0000) / 65536);
    fraction = (short) (fixed & 0x0000ffff);

    result = ((double) mantissa) + ((double) fraction) / 65536.0;

    return result;
}

When passed 0xffefaac1, for example, this function computes a
mantissa = -17, fraction = 43713, and result = -16.332993.  Is this
correct?

Thanks!
