# 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 does not suffer from the above issue, but

# it suffers from an unrelated problem whereby the combination of

# tjDecompressToYUV*() and tjDecodeYUV*() do not produce bitwise-identical

# results to tjDecompress*() 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.)
