+# NOTE: The combination of tjEncodeYUV*() and tjCompressFromYUV*() does not

+# 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
