Extend the YUV decode functionality to the TurboJPEG Java API, and port the TJUnitTest modifications that treat YUV encoding/decoding as an intermediate step of the JPEG compression/decompression pipeline rather than a separate test case; Add the ability to encode YUV images from an arbitrary position in a large image buffer; Significantly refactor the handling of YUV images; numerous doc tweaks; other Java API cleanup and usability improvements

1.4 pre-beta
============
[1] The TurboJPEG API can now be used to generate YUV images with an arbitrary
line padding (previously, it only supported 4-byte padding, which was
compatible with X Video.) Also, the decompress-to-YUV function has been
extended to support image scaling.
[1] New features in the TurboJPEG API:
-- YUV planar images can now be generated with an arbitrary line padding
(previously only 4-byte padding, which was compatible with X Video, was
supported.)
-- The decompress-to-YUV function has been extended to support image scaling.
-- JPEG images can now be compressed from YUV planar source images.
-- YUV planar images can now be decoded into RGB or grayscale images.
-- 4:1:1 subsampling is now supported. This is mainly included for
compatibility, since 4:1:1 is not fully accelerated in libjpeg-turbo and has no
significant advantages relative to 4:2:0.
-- CMYK images are now supported. This feature allows CMYK source images to be
compressed to YCCK JPEGs and YCCK or CMYK JPEGs to be decompressed to CMYK
destination images. Conversion between CMYK and RGB or YUV images is not
supported. Such conversion requires a color management system and is out of
scope for a codec library.
-- The handling of YUV images in the Java API has been significantly refactored
and should now be much more intuitive.
-- The Java API now supports encoding a YUV image from an arbitrary position in
a large image buffer.
[2] Added SIMD acceleration for DSPr2-capable MIPS platforms. This speeds up
the compression of full-color JPEGs by 70-80% on such platforms and
decompression by 25-35%.
[3] Added support for 4:1:1 subsampling to the TurboJPEG API. This is mainly
included for compatibility, since 4:1:1 is not fully accelerated in
libjpeg-turbo and has no significant advantages relative to 4:2:0.
[4] Added support for CMYK images to the TurboJPEG API. This feature allows
CMYK source images to be compressed to YCCK JPEGs and YCCK or CMYK JPEGs to be
decompressed to CMYK destination images. Conversion between CMYK and RGB
images is not supported. Such conversion requires a color management system
and is out of scope for a codec library.
[5] The TurboJPEG API can now be used to compress JPEG images from YUV planar
source images and to decode YUV planar images into RGB, grayscale, or extended
RGB images.
[6] If an application attempts to decompress a Huffman-coded JPEG image whose
[3] If an application attempts to decompress a Huffman-coded JPEG image whose
header does not contain Huffman tables, libjpeg-turbo will now insert the
default Huffman tables. In order to save space, many motion JPEG video frames
are encoded without the default Huffman tables, so these frames can now be

/**
* This class encapsulates a YUV planar image buffer and the metadata
* associated with it. The TurboJPEG API allows both the JPEG compression and
* decompression pipelines to be split into stages: YUV encode, compress from
* YUV, decompress to YUV, and YUV decode. A <code>YUVImage</code> instance
* serves as the destination image for YUV encode and decompress-to-YUV
* operations and as the source image for compress-from-YUV and YUV decode
* operations.
* <p>
* Technically, the JPEG format uses the YCbCr colorspace (which technically is
* not a "colorspace" but rather a "color transform"), but per the convention
* of the digital video community, the TurboJPEG API uses "YUV" to refer to an
* image format consisting of Y, Cb, and Cr image planes. In this image
* format, the Y, Cb (U), and Cr (V) planes are stored sequentially in the same
* image buffer, and the size of each plane is determined by the image width,
* height, line padding, and level of chrominance subsampling. If the
* chrominance components are subsampled along the horizontal dimension, then
* the width of the luminance plane would be padded to the nearest multiple of
* 2 (same goes for the height of the luminance plane, if the chrominance
* components are subsampled along the vertical dimension.) For instance, if
* the source image is 35 x 35 pixels and 4:2:2 subsampling is used, then the
* luminance plane would be 36 x 35 bytes, and each of the chrominance planes
* would be 18 x 35 bytes. If you specify, for instance, a line padding of 4
* bytes on top of this, then the luminance plane would be 36 x 35 bytes, and
* each of the chrominance planes would be 20 x 35 bytes.
