Refactor Tiled Decompression
As part of the Android patches, DRC wants Tiled compression separated out, attempt to integrate implementation into existing functionality and make sure as part of the integration it can take advantage of the huffman optimizations that have been done. New testcases and extensions to existing testcases will be needed.
Whiteboard
Headline:
libjpeg-turbo code for all architectures, now includes support for tiled based decompression.
Acceptance:
Libjpeg-turbo is able to decode using tile based decompression. Android use of this method is able to run successfully. Implementation should be integrated with current functionality such that use of the already existing Huffman optimizations is utilized. Android specific extensions to the ABI are included, new testcases are included, existing testcases are extended, and runs faster than the Android version.
