> script containing one or more scans with lengths divisible by 16 would
> result in an error ("Missing Huffman code table entry") and an invalid
> JPEG image.
> - Fixed an issue whereby tjDecodeYUV() and tjDecodeYUVPlanes() would throw
> an error ("Invalid progressive parameters") or a warning ("Inconsistent
> progression sequence") if passed a TurboJPEG instance that was previously
> used to decompress a progressive JPEG image.
