Fix Bug 671: Add JPEG Decoder w/o AWT Dependencies
Original JavaScript code from <https://github.com/notmasteryet/jpgjs/blob/master/jpg.js>, author 'notmasteryet' <async.processingjs at yahoo.com>. Ported to Java. Enhancements: * InputStream instead of memory buffer * User provided memory handler * Fixed JPEG Component ID/Index mapping * Color space conversion (YCCK, CMYK -> RGB) * More error tolerant +++ Features: JOGL AWT RGB ok ok YCCK ok Exception CMYK ok Exception YUV Store ok n/a Need Y-Flip no yes +++ Benchmark: TestJPEGJoglAWTBenchmarkNewtAWT JOGL.RGB Loops 100, dt 1199 ms, 11.99 ms/l JOGL.YUV Loops 100, dt 351 ms, 3.51 ms/l AWT.....
