- * Notes:
- *
- * This implementation makes use of 16 bit fixed point verio of two multiply
- * constants:
- *         1.   sqrt(2) * cos (pi/8)
- *         2.   sqrt(2) * sin (pi/8)
- * Becuase the first constant is bigger than 1, to maintain the same 16 bit
- * fixed point precision as the second one, we use a trick of
- *         x * a = x + x*(a-1)
- * so
- *         x * sqrt(2) * cos (pi/8) = x + x * (sqrt(2) *cos(pi/8)-1).
