# NOTE: The combination of tjEncodeYUV*() and tjCompressFromYUV*() does not
# always produce bitwise-identical results to tjCompress*() 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 tjCompressFromYUV*(), 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: nightshot_iso_100 seems to exhibit a similar phenomenon when
# decompressing. If it is scaled by a factor, such as 7/8, that causes the
# scaled width to no longer be an even multiple of the MCU width, then the
# combination of tjDecompressToYUV*() and tjDecodeYUV*() do not produce
# bitwise-identical results to tjDecompress*(). This latter phenomenon is not
# yet fully understood.)
