// The quality level is an integer number that generally ranges
// between 0 and 100, where smaller numbers indicate greater
// compression at the cost of quality, and larger numbers indicate
// higher quality but less compression.  Generally, 95 is the highest
// useful value; values between 95 and 100 produce substantially
// larger, but not substantially better, output files.  This is akin
// to the JPEG compression level.
//
// There are some special values above 100 which are generally only
// useful for debugging (specifically, to research at what point a
// particular animation artifact is being introduced):
//
//   101  Output numerically lossless data.  The output is not run
//        through the FFTCompressor.  This can be used to check
//        whether a particular artifact is due to the FFT conversion
//        or not.  However, joint angles (HPR) are still converted to
//        quaternions and normalized, discarding the fourth
//        (redundant) component.
//
//   102  As above, but the fourth quaternion component is preserved.
//
//   103  Quaternions are not used; instead, the HPR values are written
//        directly.  All output is now completely lossless; if some
//        artifacts are being introduced at this point, check your
//        sanity.
