8. Fixed an issue whereby the Java version of TJUnitTest would fail when
testing BufferedImage encoding/decoding on big endian systems.
9. Fixed a segfault in djpeg that would occur if an output format other than
PPM/PGM was selected along with the `-crop` option. The `-crop` option now
works with the GIF and Targa formats as well (unfortunately, it cannot be made
to work with the BMP and RLE formats due to the fact that those output engines
write scanlines in bottom-up order.) djpeg will now exit gracefully if an
output format other than PPM/PGM, GIF, or Targa is selected along with the
`-crop` option.
10. Fixed an issue whereby `jpeg_skip_scanlines()` would segfault if color
quantization was enabled.
11. TJBench (both C and Java versions) will now display usage information if
any command-line argument is unrecognized. This prevents the program from
silently ignoring typos.
12. Fixed an access violation in tjbench.exe (Windows) that occurred when the
program was used to decompress an existing JPEG image.
13. Fixed an ArrayIndexOutOfBoundsException in the TJExample Java program that
occurred when attempting to decompress a JPEG image that had been compressed
with 4:1:1 chrominance subsampling.
