Comment (by bdubbs@…):
### Significant changes relative to 1.5.2:
1. Fixed a NullPointerException in the TurboJPEG Java wrapper that
occurred when using the YUVImage constructor that creates an instance
backed by separate image planes and allocates memory for the image planes.
2. Fixed an issue whereby the Java version of TJUnitTest would fail when
testing BufferedImage encoding/decoding on big endian systems.
3. 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.
4. Fixed an issue whereby `jpeg_skip_scanlines()` would segfault if color
quantization was enabled.
5. TJBench (both C and Java versions) will now display usage information
if any command-line argument is unrecognized. This prevents the program
from silently gnoring typos.
6. Fixed an access violation in tjbench.exe (Windows) that occurred when
the program was used to decompress an existing JPEG image.
7. 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.
8. Fixed an issue whereby, when using `jpeg_skip_scanlines()` to skip to
the end of a single-scan (non-progressive) image, subsequent calls to
`jpeg_consume_input()` would return `JPEG_SUSPENDED` rather than
`JPEG_REACHED_EOI`.
9. `jpeg_crop_scanlines()` now works correctly when decompressing
grayscale JPEG images that were compressed with a sampling factor other
than 1 (for instance, with `cjpeg -grayscale -sample 2x2`).
