+# 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.)
