  - Update from version 3.0.3 to 3.0.4
- Update of rootfile not required
- Changelog
    3.0.4
	1. Fixed an issue whereby the CPU usage of the default marker processor in the
	decompressor grew exponentially with the number of markers.  This caused an
	unreasonable slow-down in `jpeg_read_header()` if an application called
	`jpeg_save_markers()` to save markers of a particular type and then attempted
	to decompress a JPEG image containing an excessive number of markers of that
	type.
	2. Hardened the default marker processor in the decompressor to guard against
	an issue (exposed by 3.0 beta2[6]) whereby attempting to decompress a
	specially-crafted malformed JPEG image (specifically an image with a complete
	12-bit-per-sample Start Of Frame segment followed by an incomplete
	8-bit-per-sample Start Of Frame segment) using buffered-image mode and input
	prefetching caused a segfault if the `fill_input_buffer()` method in the
	calling application's custom source manager incorrectly returned `FALSE` in
	response to a prematurely-terminated JPEG data stream.
	3. Fixed an issue in cjpeg whereby, when generating a 12-bit-per-sample or
	16-bit-per-sample lossless JPEG image, specifying a point transform value
	greater than 7 resulted in an error ("Invalid progressive/lossless parameters")
	unless the `-precision` option was specified before the `-lossless` option.
	4. Fixed a regression introduced by 3.0.3[3] that made it impossible for
	calling applications to generate 12-bit-per-sample arithmetic-coded lossy JPEG
	images using the TurboJPEG API.
	5. Fixed an error ("Destination buffer is not large enough") that occurred when
	attempting to generate a full-color lossless JPEG image using the TurboJPEG
	Java API's `byte[] TJCompressor.compress()` method if the value of
	`TJ.PARAM_SUBSAMP` was not `TJ.SAMP_444`.
	6. Fixed a segfault in djpeg that occurred if a negative width was specified
	with the `-crop` option.  Since the cropping region width was read into an
	unsigned 32-bit integer, a negative width was interpreted as a very large
	value.  With certain negative width and positive left boundary values, the
	bounds checks in djpeg and `jpeg_crop_scanline()` overflowed and did not detect
	the out-of-bounds width, which caused a buffer overrun in the upsampling or
	color conversion routine.  Both bounds checks now use 64-bit integers to guard
	against overflow, and djpeg now checks for negative numbers when it parses the
	crop specification from the command line.
	7. Fixed an issue whereby the TurboJPEG lossless transformation function and
	methods checked the specified cropping region against the source image
	dimensions and level of chrominance subsampling rather than the destination
	image dimensions and level of chrominance subsampling, which caused some
	cropping regions to be unduly rejected when performing 90-degree rotation,
	270-degree rotation, transposition, transverse transposition, or grayscale
	conversion.
	8. Fixed an issue whereby the TurboJPEG lossless transformation function and
	methods did not honor `TJXOPT_COPYNONE`/`TJTransform.OPT_COPYNONE` unless it
	was specified for all lossless transforms.
