  1. Add support for 16-bit precision JPEG quantization values 

    Don't force JPEG quantization to be baseline-compatible

Quantization values will not be limited to values 1..255 and may
be 16 bits if needed. This may cause compatibility issues.

  3. Keep baseline compatibility when specifying quality 

    16-bit quantization tables can appear at quality values below
about 25. These may cause compatibility problems. Maintain
baseline compatibility and avoid confusing users with warning
messages.
