b212a1eb8f 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.

6db0843af4 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.
