This is still confusing as it is still confusing arithmetic coding with
"lossless JPEG".  Arithmetic coding, with DCT JPEG performs better than
the JFIF library Huffman only baseline JPEG that is used on the web.
"lossless JPEG" is something different, although standardised at about
the same time, and it is that, not arithmetic coding, that performs
poorly.
