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
