- Update to version 3.0.4
  * 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`.
