====================================

Changes from OpenJPEG 1.5.x to OpenJPEG 2.0.0
----------------------------------------------

New Features:

    * streaming capabilities
    * merge JP3D

API modifications:

    * Use a 64bits capable API
    
Misc:

    * removed autotools build system
    * folders hierarchies reorganisation

 * 	libjpeg, with longjump stuff, are encapsulated in dedicated functions. When
 * 	JPEG_ENCAP_EXTERNAL is defined, these encapsulating functions are declared external
 * 	to this unit, and can be defined elsewhere to use stuff other then longjump.
 * 	The default mode, without JPEG_ENCAP_EXTERNAL, implements the call encapsulators
 * 	here, internally, with normal longjump.
 * SETJMP, LONGJMP, JMP_BUF: On some machines/environments a longjump equivalent is
 * 	conviniently available, but still it may be worthwhile to use _setjmp or sigsetjmp
 * 	in place of plain setjmp. These macros will make it easier. It is useless
 * 	to fiddle with these if you define JPEG_ENCAP_EXTERNAL.
 * OJPEG_BUFFER: Define the size of the desired buffer here. Should be small enough so as to guarantee
 * 	instant processing, optimal streaming and optimal use of processor cache, but also big
 * 	enough so as to not result in significant call overhead. It should be at least a few
 * 	bytes to accommodate some structures (this is verified in asserts), but it would not be
 * 	sensible to make it this small anyway, and it should be at most 64K since it is indexed
 * 	with uint16. We recommend 2K.
 * EGYPTIANWALK: You could also define EGYPTIANWALK here, but it is not used anywhere and has
 * 	absolutely no effect. That is why most people insist the EGYPTIANWALK is a bit silly.
