+January 2, 2011
+* [antonin] bug fixes to enable cmake compilation on WIN32 platform
+ - fixed getopt bug in jpwl/CMakeLists.txt
+ - added png, zlib and lcms win32 libraries to libs directory
+ - updated libs/libtiff library
+ - moved j2k_dump_{image,cp} to j2k_dump.c to remain consistent with API interface
+ - changed mj2 cmake compilation method: as long as mj2 binaries do not strictly use the API interface, libopenjpeg source files are directly included in mj2 executables compilation.
+! [antonin] small update to xcode project

+ * for applications, is an unsigned integer of the form xyyzz corresponding
+ * to the source version x.y.z (leading zeros in y and z). Beta versions
+ * were given the previous public release number plus a letter, until
+ * version 1.0.6j; from then on they were given the upcoming public
+ * release number plus "betaNN" or "rcN".
+ *
+ * Binary incompatibility exists only when applications make direct access
+ * to the info_ptr or png_ptr members through png.h, and the compiled
+ * application is loaded with a different version of the library.
+ *
+ * DLLNUM will change each time there are forward or backward changes
+ * in binary compatibility (e.g., when a new feature is added).
+ *
+ * See libpng.txt or libpng.3 for more information. The PNG specification

+ * Y2K compliance in libpng:
+ * =========================
+ *
+ * September 23, 2010
+ *
+ * Since the PNG Development group is an ad-hoc body, we can't make
+ * an official declaration.
+ *
+ * This is your unofficial assurance that libpng from version 0.71 and
+ * upward through 1.4.4 are Y2K compliant. It is my belief that earlier
+ * versions were also Y2K compliant.
+ *
+ * Libpng only has three year fields. One is a 2-byte unsigned integer
+ * that will hold years up to 65535. The other two hold the date in text
+ * format, and will hold years up to 9999.
+ *
+ * The integer is
+ * "png_uint_16 year" in png_time_struct.
+ *
+ * The strings are
+ * "png_charp time_buffer" in png_struct and
+ * "near_time_buffer", which is a local character string in png.c.
+ *
+ * There are seven time-related functions:
+ * png.c: png_convert_to_rfc_1123() in png.c
+ * (formerly png_convert_to_rfc_1152() in error)
+ * png_convert_from_struct_tm() in pngwrite.c, called in pngwrite.c
+ * png_convert_from_time_t() in pngwrite.c
+ * png_get_tIME() in pngget.c
+ * png_handle_tIME() in pngrutil.c, called in pngread.c
+ * png_set_tIME() in pngset.c
+ * png_write_tIME() in pngwutil.c, called in pngwrite.c
+ *
+ * All handle dates properly in a Y2K environment. The
+ * png_convert_from_time_t() function calls gmtime() to convert from system
+ * clock time, which returns (year - 1900), which we properly convert to
+ * the full 4-digit year. There is a possibility that applications using
+ * libpng are not passing 4-digit years into the png_convert_to_rfc_1123()
+ * function, or that they are incorrectly passing only a 2-digit year
+ * instead of "year - 1900" into the png_convert_from_struct_tm() function,
+ * but this is not under our control. The libpng documentation has always
+ * stated that it works with 4-digit years, and the APIs have been
+ * documented as such.
+ *
+ * The tIME chunk itself is also Y2K compliant. It uses a 2-byte unsigned
+ * integer to hold the year, and can hold years as large as 65535.
+ *
+ * zlib, upon which libpng depends, is also Y2K compliant. It contains
+ * no date-related code.

+ The 'zlib' compression library provides in-memory compression and\r
+ decompression functions, including integrity checks of the uncompressed\r
+ data. This version of the library supports only one compression method\r
+ (deflation) but other algorithms will be added later and will have the same\r
+ stream interface.\r
+\r
+ Compression can be done in a single step if the buffers are large\r
+ enough (for example if an input file is mmap'ed), or can be done by\r
+ repeated calls of the compression function. In the latter case, the\r
+ application must provide more input and/or consume the output\r
+ (providing more output space) before each call.\r
+\r
+ The compressed data format used by default by the in-memory functions is\r
+ the zlib format, which is a zlib wrapper documented in RFC 1950, wrapped\r
+ around a deflate stream, which is itself documented in RFC 1951.\r
+\r
+ The library also supports reading and writing files in gzip (.gz) format\r
+ with an interface similar to that of stdio using the functions that start\r
+ with "gz". The gzip format is different from the zlib format. gzip is a\r
+ gzip wrapper, documented in RFC 1952, wrapped around a deflate stream.\r
+\r
+ This library can optionally read and write gzip streams in memory as well.\r
+\r
+ The zlib format was designed to be compact and fast for use in memory\r
+ and on communications channels. The gzip format was designed for single-\r
+ file compression on file systems, has a larger header than zlib to maintain\r
+ directory information, and uses a different, slower check method than zlib.\r
+\r
+ The library does not install any signal handler. The decoder checks\r
+ the consistency of the compressed data, so the library should never\r
+ crash even in case of corrupted input.\r

+ deflate compresses as much data as possible, and stops when the input\r

+ output latency (reading input without producing any output) except when\r
+ forced to flush.\r
+\r
+ The detailed semantics are as follows. deflate performs one or both of the\r
+ following actions:\r
+\r
+ - Compress more input starting at next_in and update next_in and avail_in\r
+ accordingly. If not all input can be processed (because there is not\r
+ enough room in the output buffer), next_in and avail_in are updated and\r
+ processing will resume at this point for the next call of deflate().\r
+\r
+ - Provide more output starting at next_out and update next_out and avail_out\r
+ accordingly. This action is forced if the parameter flush is non zero.\r
+ Forcing flush frequently degrades the compression ratio, so this parameter\r
+ should be set only when necessary (in interactive applications).\r
+ Some output may be provided even if flush is not set.\r
+\r
+ Before the call of deflate(), the application should ensure that at least\r
+ one of the actions is possible, by providing more input and/or consuming\r
+ more output, and updating avail_in or avail_out accordingly; avail_out\r
+ should never be zero before the call. The application can consume the\r
+ compressed output when it wants, for example when the output buffer is full\r
+ (avail_out == 0), or after each call of deflate(). If deflate returns Z_OK\r
+ and with zero avail_out, it must be called again after making room in the\r
+ output buffer because there might be more output pending.\r
+\r
+ Normally the parameter flush is set to Z_NO_FLUSH, which allows deflate to\r
+ decide how much data to accumualte before producing output, in order to\r
+ maximize compression.\r
+\r
+ If the parameter flush is set to Z_SYNC_FLUSH, all pending output is\r
+ flushed to the output buffer and the output is aligned on a byte boundary, so\r
+ that the decompressor can get all input data available so far. (In particular\r
+ avail_in is zero after the call if enough output space has been provided\r
+ before the call.) Flushing may degrade compression for some compression\r
+ algorithms and so it should be used only when necessary.\r
+\r
+ If flush is set to Z_FULL_FLUSH, all output is flushed as with\r
+ Z_SYNC_FLUSH, and the compression state is reset so that decompression can\r
+ restart from this point if previous compressed data has been damaged or if\r
+ random access is desired. Using Z_FULL_FLUSH too often can seriously degrade\r
+ compression.\r
+\r
+ If deflate returns with avail_out == 0, this function must be called again\r
+ with the same value of the flush parameter and more output space (updated\r
+ avail_out), until the flush is complete (deflate returns with non-zero\r
+ avail_out). In the case of a Z_FULL_FLUSH or Z_SYNC_FLUSH, make sure that\r
+ avail_out is greater than six to avoid repeated flush markers due to\r
+ avail_out == 0 on return.\r
+\r
+ If the parameter flush is set to Z_FINISH, pending input is processed,\r
+ pending output is flushed and deflate returns with Z_STREAM_END if there\r
+ was enough output space; if deflate returns with Z_OK, this function must be\r
+ called again with Z_FINISH and more output space (updated avail_out) but no\r
+ more input data, until it returns with Z_STREAM_END or an error. After\r
+ deflate has returned Z_STREAM_END, the only possible operations on the\r
+ stream are deflateReset or deflateEnd.\r
+\r
+ Z_FINISH can be used immediately after deflateInit if all the compression\r
+ is to be done in a single step. In this case, avail_out must be at least\r
+ the value returned by deflateBound (see below). If deflate does not return\r
+ Z_STREAM_END, then it must be called again as described above.\r

+\r
+ Before the call of inflate(), the application should ensure that at least\r

+ call of inflate(). If inflate returns Z_OK and with zero avail_out, it\r
+ must be called again after making room in the output buffer because there\r
+ might be more output pending.\r
+\r
+ The flush parameter of inflate() can be Z_NO_FLUSH, Z_SYNC_FLUSH,\r
+ Z_FINISH, or Z_BLOCK. Z_SYNC_FLUSH requests that inflate() flush as much\r
+ output as possible to the output buffer. Z_BLOCK requests that inflate() stop\r
+ if and when it gets to the next deflate block boundary. When decoding the\r
+ zlib or gzip format, this will cause inflate() to return immediately after\r
+ the header and before the first block. When doing a raw inflate, inflate()\r
+ will go ahead and process the first block, and will return when it gets to\r
+ the end of that block, or when it runs out of data.\r
+\r
+ The Z_BLOCK option assists in appending to or combining deflate streams.\r
+ Also to assist in this, on return inflate() will set strm->data_type to the\r
+ number of unused bits in the last byte taken from strm->next_in, plus 64\r
+ if inflate() is currently decoding the last block in the deflate stream,\r
+ plus 128 if inflate() returned immediately after decoding an end-of-block\r
+ code or decoding the complete header up to just before the first byte of the\r
+ deflate stream. The end-of-block will not be indicated until all of the\r
+ uncompressed data from that block has been written to strm->next_out. The\r
+ number of unused bits may in general be greater than seven, except when\r
+ bit 7 of data_type is set, in which case the number of unused bits will be\r
+ less than eight.\r
+\r
+ inflate() should normally be called until it returns Z_STREAM_END or an\r
+ error. However if all decompression is to be performed in a single step\r
+ (a single call of inflate), the parameter flush should be set to\r
+ Z_FINISH. In this case all pending input is processed and all pending\r
+ output is flushed; avail_out must be large enough to hold all the\r
+ uncompressed data. (The size of the uncompressed data may have been saved\r
+ by the compressor for this purpose.) The next operation on this stream must\r
+ be inflateEnd to deallocate the decompression state. The use of Z_FINISH\r
+ is never required, but can be used to inform inflate that a faster approach\r
+ may be used for the single inflate() call.\r
+\r
+ In this implementation, inflate() always flushes as much output as\r
+ possible to the output buffer, and always uses the faster approach on the\r
+ first call. So the only effect of the flush parameter in this implementation\r
+ is on the return value of inflate(), as noted below, or when it returns early\r
+ because Z_BLOCK is used.\r
+\r
+ If a preset dictionary is needed after this call (see inflateSetDictionary\r
+ below), inflate sets strm->adler to the adler32 checksum of the dictionary\r
+ chosen by the compressor and returns Z_NEED_DICT; otherwise it sets\r
+ strm->adler to the adler32 checksum of all output produced so far (that is,\r
+ total_out bytes) and returns Z_OK, Z_STREAM_END or an error code as described\r
+ below. At the end of the stream, inflate() checks that its computed adler32\r
+ checksum is equal to that saved by the compressor and returns Z_STREAM_END\r
+ only if the checksum is correct.\r
+\r
+ inflate() will decompress and check either zlib-wrapped or gzip-wrapped\r
+ deflate data. The header type is detected automatically. Any information\r
+ contained in the gzip header is not retained, so applications that need that\r
+ information should instead use raw inflate, see inflateInit2() below, or\r

+\r
+ This is another version of deflateInit with more compression options. The\r
+ fields next_in, zalloc, zfree and opaque must be initialized before by\r
+ the caller.\r
+\r
+ The method parameter is the compression method. It must be Z_DEFLATED in\r
+ this version of the library.\r
+\r
+ The windowBits parameter is the base two logarithm of the window size\r
+ (the size of the history buffer). It should be in the range 8..15 for this\r
+ version of the library. Larger values of this parameter result in better\r
+ compression at the expense of memory usage. The default value is 15 if\r
+ deflateInit is used instead.\r
+\r
+ windowBits can also be -8..-15 for raw deflate. In this case, -windowBits\r
+ determines the window size. deflate() will then generate raw deflate data\r
+ with no zlib header or trailer, and will not compute an adler32 check value.\r
+\r
+ windowBits can also be greater than 15 for optional gzip encoding. Add\r
+ 16 to windowBits to write a simple gzip header and trailer around the\r
+ compressed data instead of a zlib wrapper. The gzip header will have no\r
+ file name, no extra data, no comment, no modification time (set to zero),\r
+ no header crc, and the operating system will be set to 255 (unknown). If a\r
+ gzip stream is being written, strm->adler is a crc32 instead of an adler32.\r
+\r
+ The memLevel parameter specifies how much memory should be allocated\r
+ for the internal compression state. memLevel=1 uses minimum memory but\r
+ is slow and reduces compression ratio; memLevel=9 uses maximum memory\r
+ for optimal speed. The default value is 8. See zconf.h for total memory\r
+ usage as a function of windowBits and memLevel.\r
+\r
+ The strategy parameter is used to tune the compression algorithm. Use the\r
+ value Z_DEFAULT_STRATEGY for normal data, Z_FILTERED for data produced by a\r
+ filter (or predictor), Z_HUFFMAN_ONLY to force Huffman encoding only (no\r
+ string match), or Z_RLE to limit match distances to one (run-length\r
+ encoding). Filtered data consists mostly of small values with a somewhat\r
+ random distribution. In this case, the compression algorithm is tuned to\r
+ compress them better. The effect of Z_FILTERED is to force more Huffman\r
+ coding and less string matching; it is somewhat intermediate between\r
+ Z_DEFAULT and Z_HUFFMAN_ONLY. Z_RLE is designed to be almost as fast as\r
+ Z_HUFFMAN_ONLY, but give better compression for PNG image data. The strategy\r
+ parameter only affects the compression ratio but not the correctness of the\r
+ compressed output even if it is not set appropriately. Z_FIXED prevents the\r
+ use of dynamic Huffman codes, allowing for a simpler decoder for special\r
+ applications.\r

+\r
+ A raw deflate stream is one with no zlib or gzip header or trailer.\r
+ This routine would normally be used in a utility that reads zip or gzip\r

+ header and process the trailer on its own, hence this routine expects\r
+ only the raw deflate stream to decompress. This is different from the\r
+ normal behavior of inflate(), which expects either a zlib or gzip header and\r
+ trailer around the deflate stream.\r
+\r
+ inflateBack() uses two subroutines supplied by the caller that are then\r
+ called by inflateBack() for input and output. inflateBack() calls those\r
+ routines until it reads a complete deflate stream and writes out all of the\r
+ uncompressed data, or until it encounters an error. The function's\r
+ parameters and return types are defined above in the in_func and out_func\r
+ typedefs. inflateBack() will call in(in_desc, &buf) which should return the\r
+ number of bytes of provided input, and a pointer to that input in buf. If\r
+ there is no input available, in() must return zero--buf is ignored in that\r
+ case--and inflateBack() will return a buffer error. inflateBack() will call\r
+ out(out_desc, buf, len) to write the uncompressed data buf[0..len-1]. out()\r
+ should return zero on success, or non-zero on failure. If out() returns\r
+ non-zero, inflateBack() will return with an error. Neither in() nor out()\r
+ are permitted to change the contents of the window provided to\r
+ inflateBackInit(), which is also the buffer that out() uses to write from.\r
+ The length written by out() will be at most the window size. Any non-zero\r
+ amount of input may be provided by in().\r
+\r
+ For convenience, inflateBack() can be provided input on the first call by\r
+ setting strm->next_in and strm->avail_in. If that input is exhausted, then\r
+ in() will be called. Therefore strm->next_in must be initialized before\r
+ calling inflateBack(). If strm->next_in is Z_NULL, then in() will be called\r
+ immediately for input. If strm->next_in is not Z_NULL, then strm->avail_in\r
+ must also be initialized, and then if strm->avail_in is not zero, input will\r
+ initially be taken from strm->next_in[0 .. strm->avail_in - 1].\r

+\r
+ On return, inflateBack() will set strm->next_in and strm->avail_in to\r
+ pass back any unused input that was provided by the last in() call. The\r
+ return values of inflateBack() can be Z_STREAM_END on success, Z_BUF_ERROR\r
+ if in() or out() returned an error, Z_DATA_ERROR if there was a format\r
+ error in the deflate stream (in which case strm->msg is set to indicate the\r
+ nature of the error), or Z_STREAM_ERROR if the stream was not properly\r
+ initialized. In the case of Z_BUF_ERROR, an input or output error can be\r
+ distinguished using strm->next_in which will be Z_NULL only if in() returned\r
+ an error. If strm->next is not Z_NULL, then the Z_BUF_ERROR was due to\r
+ out() returning non-zero. (in() will always be called before out(), so\r
