* 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.
* 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.
* 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.
* 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.
* 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`.
