00050     Comments:
00051       We read code stream syntax and JP2, but we write always as JP2.
00052       Used definitions EXCLUDE_JPG_SUPPORT,EXCLUDE_MIF_SUPPORT,
00053                        EXCLUDE_PNM_SUPPORT,EXCLUDE_RAS_SUPPORT,
00054                        EXCLUDE_BMP_SUPPORT,EXCLUDE_PGX_SUPPORT
00055       Changed jas_config.h to match our needs.
00056       New file jas_binfile.c
00057       Changed jas_stream.c to export jas_stream_create and jas_stream_initbuf.
00058       Changed jp2_dec.c and jpc_cs.c to remove "uint" and "ulong" usage.
