DRC 96bc40c1b3 Implement arithmetic coding with 12-bit precision 
This actually works and apparently always has worked.  It only failed
because the libjpeg code, which did not originally support arithmetic
coding, assumed that optimize_coding should always be TRUE for 12-bit
data precision.

# NOTE: The combination of tj3EncodeYUV*() and tj3CompressFromYUV*() does not
# always produce bitwise-identical results to tj3Compress*() if subsampling is
# enabled. In both cases, if the image width or height are not evenly
# divisible by the MCU width/height, then the bottom and/or right edge are
# expanded. However, the libjpeg code performs this expansion prior to
# downsampling, and TurboJPEG performs it in tj3CompressFromYUV*(), which is
# after downsampling. Thus, the two will agree only if the width/height along
# each downsampled dimension is an odd number or is evenly divisible by the MCU
# width/height. This disagreement basically amounts to a round-off error, but
# there is no easy way around it, so for now, we just test the only image that
# works. (NOTE: big_tree8 does not suffer from the above issue, but it suffers
# from an unrelated problem whereby the combination of tj3DecompressToYUV*()
# and tj3DecodeYUV*() do not produce bitwise-identical results to
# tj3Decompress*() if decompression scaling is enabled. This latter phenomenon
# is not yet fully understood but is also believed to be some sort of round-off
# error.)
