+ * Note that the number of samples fetched by the FDCT routine is
+ * DCT_h_scaled_size * DCT_v_scaled_size.
  * The DCT outputs are returned scaled up by a factor of 8; they therefore
  * have a range of +-8K for 8-bit data, +-128K for 12-bit data.  This
  * convention improves accuracy in integer implementations and saves some
