Initial import from the monolithic Qt.

This is the beginning of revision history for this module. If you want to look at revision history older than this, please refer to the Qt Git wiki for how to use Git history grafting. At the time of writing, this wiki is located here: http://qt.gitorious.org/qt/pages/GitIntroductionWithQt If you have already performed the grafting and you don't see any history beyond this commit, try running "git log" with the "--follow" argument. Branched from the monolithic repo, Qt master branch, at commit 896db169ea224deb96c59ce8af800d019de63f12

+Low-level file handling
+~~~~~~~~~~~~~~~~~~~~~~~
+The functions in osfcn.h are unavailable when compiling under C, as it's a
+C++ header. Therefore they have been implemented here.
+
+Now, why have I done it this way?
+
+The definitive API library for RISC OS is Jonathan Coxhead's OSLib, which
+uses heavily optimised ARM assembler or even plain inline SWI calls for
+maximum performance and minimum runtime size. However, I don't want to make
+LIBTIFF need that to survive. Therefore I have also emulated the functions
+using macros to _swi() and _swix() defined in the swis.h header, and
+borrowing types from kernel.h, which is less efficient but doesn't need any
+third-party libraries.

+ * TIFF Library Macintosh-specific routines.
+ *
+ * These routines use only Toolbox and high-level File Manager traps.
+ * They make no calls to the THINK C "unix" compatibility library.  Also,
+ * malloc is not used directly but it is still referenced internally by
+ * the ANSI library in rare cases.  Heap fragmentation by the malloc ring
+ * buffer is therefore minimized.
+ *
+ * O_RDONLY and O_RDWR are treated identically here.  The tif_mode flag is
+ * checked in TIFFWriteCheck().
+ *
+ * Create below fills in a blank creator signature and sets the file type
+ * to 'TIFF'.  It is much better for the application to do this by Create'ing
+ * the file first and TIFFOpen'ing it later.
+ * ---------
+ * This code has been "Carbonized", and may not work with older MacOS versions.
+ * If so, grab the tif_apple.c out of an older libtiff distribution, like
+ * 3.5.5 from www.libtiff.org.

+ * TIFF Library.
+ * LogLuv compression support for high dynamic range images.
+ *
+ * Contributed by Greg Larson.
+ *
+ * LogLuv image support uses the TIFF library to store 16 or 10-bit
+ * log luminance values with 8 bits each of u and v or a 14-bit index.
+ *
+ * The codec can take as input and produce as output 32-bit IEEE float values 
+ * as well as 16-bit integer values.  A 16-bit luminance is interpreted
+ * as a sign bit followed by a 15-bit integer that is converted
+ * to and from a linear magnitude using the transformation:
+ *
+ *	L = 2^( (Le+.5)/256 - 64 )		# real from 15-bit
+ *
+ *	Le = floor( 256*(log2(L) + 64) )	# 15-bit from real
+ *
+ * The actual conversion to world luminance units in candelas per sq. meter
+ * requires an additional multiplier, which is stored in the TIFFTAG_STONITS.
+ * This value is usually set such that a reasonable exposure comes from
+ * clamping decoded luminances above 1 to 1 in the displayed image.
+ *
+ * The 16-bit values for u and v may be converted to real values by dividing
+ * each by 32768.  (This allows for negative values, which aren't useful as
+ * far as we know, but are left in case of future improvements in human
+ * color vision.)
+ *
+ * Conversion from (u,v), which is actually the CIE (u',v') system for
+ * you color scientists, is accomplished by the following transformation:
+ *
+ *	u = 4*x / (-2*x + 12*y + 3)
+ *	v = 9*y / (-2*x + 12*y + 3)
+ *
+ *	x = 9*u / (6*u - 16*v + 12)
+ *	y = 4*v / (6*u - 16*v + 12)
+ *
+ * This process is greatly simplified by passing 32-bit IEEE floats
+ * for each of three CIE XYZ coordinates.  The codec then takes care
+ * of conversion to and from LogLuv, though the application is still
+ * responsible for interpreting the TIFFTAG_STONITS calibration factor.
+ *
+ * By definition, a CIE XYZ vector of [1 1 1] corresponds to a neutral white
+ * point of (x,y)=(1/3,1/3).  However, most color systems assume some other
+ * white point, such as D65, and an absolute color conversion to XYZ then
+ * to another color space with a different white point may introduce an
+ * unwanted color cast to the image.  It is often desirable, therefore, to
+ * perform a white point conversion that maps the input white to [1 1 1]
+ * in XYZ, then record the original white point using the TIFFTAG_WHITEPOINT
+ * tag value.  A decoder that demands absolute color calibration may use
+ * this white point tag to get back the original colors, but usually it
+ * will be ignored and the new white point will be used instead that
+ * matches the output color space.
+ *
+ * Pixel information is compressed into one of two basic encodings, depending
+ * on the setting of the compression tag, which is one of COMPRESSION_SGILOG
+ * or COMPRESSION_SGILOG24.  For COMPRESSION_SGILOG, greyscale data is
+ * stored as:
+ *
+ *	 1       15
+ *	|-+---------------|
+ *
+ * COMPRESSION_SGILOG color data is stored as:
+ *
+ *	 1       15           8        8
+ *	|-+---------------|--------+--------|
+ *	 S       Le           ue       ve
+ *
+ * For the 24-bit COMPRESSION_SGILOG24 color format, the data is stored as:
+ *
+ *	     10           14
+ *	|----------|--------------|
+ *	     Le'          Ce
+ *
+ * There is no sign bit in the 24-bit case, and the (u,v) chromaticity is
+ * encoded as an index for optimal color resolution.  The 10 log bits are
+ * defined by the following conversions:
+ *
+ *	L = 2^((Le'+.5)/64 - 12)		# real from 10-bit
+ *
+ *	Le' = floor( 64*(log2(L) + 12) )	# 10-bit from real
+ *
+ * The 10 bits of the smaller format may be converted into the 15 bits of
+ * the larger format by multiplying by 4 and adding 13314.  Obviously,
+ * a smaller range of magnitudes is covered (about 5 orders of magnitude
+ * instead of 38), and the lack of a sign bit means that negative luminances
+ * are not allowed.  (Well, they aren't allowed in the real world, either,
+ * but they are useful for certain types of image processing.)
+ *
+ * The desired user format is controlled by the setting the internal
+ * pseudo tag TIFFTAG_SGILOGDATAFMT to one of:
+ *  SGILOGDATAFMT_FLOAT       = IEEE 32-bit float XYZ values
+ *  SGILOGDATAFMT_16BIT	      = 16-bit integer encodings of logL, u and v
+ * Raw data i/o is also possible using:
+ *  SGILOGDATAFMT_RAW         = 32-bit unsigned integer with encoded pixel
+ * In addition, the following decoding is provided for ease of display:
+ *  SGILOGDATAFMT_8BIT        = 8-bit default RGB gamma-corrected values
+ *
+ * For grayscale images, we provide the following data formats:
+ *  SGILOGDATAFMT_FLOAT       = IEEE 32-bit float Y values
+ *  SGILOGDATAFMT_16BIT       = 16-bit integer w/ encoded luminance
+ *  SGILOGDATAFMT_8BIT        = 8-bit gray monitor values
+ *
+ * Note that the COMPRESSION_SGILOG applies a simple run-length encoding
+ * scheme by separating the logL, u and v bytes for each row and applying
+ * a PackBits type of compression.  Since the 24-bit encoding is not
+ * adaptive, the 32-bit color format takes less space in many cases.
+ *
+ * Further control is provided over the conversion from higher-resolution
+ * formats to final encoded values through the pseudo tag
+ * TIFFTAG_SGILOGENCODE:
+ *  SGILOGENCODE_NODITHER     = do not dither encoded values
+ *  SGILOGENCODE_RANDITHER    = apply random dithering during encoding
+ *
+ * The default value of this tag is SGILOGENCODE_NODITHER for
+ * COMPRESSION_SGILOG to maximize run-length encoding and
+ * SGILOGENCODE_RANDITHER for COMPRESSION_SGILOG24 to turn
+ * quantization errors into noise.

+
+/* What is what, and what is not?
+
+   This decoder starts with an input stream, that is essentially the JpegInterchangeFormat
+   stream, if any, followed by the strile data, if any. This stream is read in
+   OJPEGReadByte and related functions.
+
+   It analyzes the start of this stream, until it encounters non-marker data, i.e.
+   compressed image data. Some of the header markers it sees have no actual content,
+   like the SOI marker, and APP/COM markers that really shouldn't even be there. Some
+   other markers do have content, and the valuable bits and pieces of information
+   in these markers are saved, checking all to verify that the stream is more or
+   less within expected bounds. This happens inside the OJPEGReadHeaderInfoSecStreamXxx
+   functions.
+
+   Some OJPEG imagery contains no valid JPEG header markers. This situation is picked
+   up on if we've seen no SOF marker when we're at the start of the compressed image
+   data. In this case, the tables are read from JpegXxxTables tags, and the other
+   bits and pieces of information is initialized to its most basic value. This is
+   implemented in the OJPEGReadHeaderInfoSecTablesXxx functions.
+
+   When this is complete, a good and valid JPEG header can be assembled, and this is
+   passed through to LibJpeg. When that's done, the remainder of the input stream, i.e.
+   the compressed image data, can be passed through unchanged. This is done in
+   OJPEGWriteStream functions.
+
+   LibTiff rightly expects to know the subsampling values before decompression. Just like
+   in new-style JPEG-in-TIFF, though, or even more so, actually, the YCbCrsubsampling
+   tag is notoriously unreliable. To correct these tag values with the ones inside
+   the JPEG stream, the first part of the input stream is pre-scanned in
+   OJPEGSubsamplingCorrect, making no note of any other data, reporting no warnings
+   or errors, up to the point where either these values are read, or it's clear they
+   aren't there. This means that some of the data is read twice, but we feel speed
+   in correcting these values is important enough to warrant this sacrifice. Allthough
+   there is currently no define or other configuration mechanism to disable this behaviour,
+   the actual header scanning is build to robustly respond with error report if it
+   should encounter an uncorrected mismatch of subsampling values. See
+   OJPEGReadHeaderInfoSecStreamSof.
+
+   The restart interval and restart markers are the most tricky part... The restart
+   interval can be specified in a tag. It can also be set inside the input JPEG stream.
+   It can be used inside the input JPEG stream. If reading from strile data, we've
+   consistenly discovered the need to insert restart markers in between the different
+   striles, as is also probably the most likely interpretation of the original TIFF 6.0
+   specification. With all this setting of interval, and actual use of markers that is not
+   predictable at the time of valid JPEG header assembly, the restart thing may turn
+   out the Achilles heel of this implementation. Fortunately, most OJPEG writer vendors
+   succeed in reading back what they write, which may be the reason why we've been able
+   to discover ways that seem to work.
+
+   Some special provision is made for planarconfig separate OJPEG files. These seem
+   to consistently contain header info, a SOS marker, a plane, SOS marker, plane, SOS,
+   and plane. This may or may not be a valid JPEG configuration, we don't know and don't
+   care. We want LibTiff to be able to access the planes individually, without huge
+   buffering inside LibJpeg, anyway. So we compose headers to feed to LibJpeg, in this
+   case, that allow us to pass a single plane such that LibJpeg sees a valid
+   single-channel JPEG stream. Locating subsequent SOS markers, and thus subsequent
+   planes, is done inside OJPEGReadSecondarySos.
+
+   The benefit of the scheme is... that it works, basically. We know of no other that
+   does. It works without checking software tag, or otherwise going about things in an
+   OJPEG flavor specific manner. Instead, it is a single scheme, that covers the cases
+   with and without JpegInterchangeFormat, with and without striles, with part of
+   the header in JpegInterchangeFormat and remainder in first strile, etc. It is forgiving
+   and robust, may likely work with OJPEG flavors we've not seen yet, and makes most out
+   of the data.
+
+   Another nice side-effect is that a complete JPEG single valid stream is build if
+   planarconfig is not separate (vast majority). We may one day use that to build
+   converters to JPEG, and/or to new-style JPEG compression inside TIFF.
+
+   A dissadvantage is the lack of random access to the individual striles. This is the
+   reason for much of the complicated restart-and-position stuff inside OJPEGPreDecode.
+   Applications would do well accessing all striles in order, as this will result in
+   a single sequential scan of the input stream, and no restarting of LibJpeg decoding
+   session.

+	 * TIFF but only supports some braindead idea of what the
+	 * vendor thinks TIFF is):
+	 *
+	 * 'l'		use little-endian byte order for creating a file
+	 * 'b'		use big-endian byte order for creating a file
+	 * 'L'		read/write information using LSB2MSB bit order
+	 * 'B'		read/write information using MSB2LSB bit order
+	 * 'H'		read/write information using host bit order
+	 * 'M'		enable use of memory-mapped files when supported
+	 * 'm'		disable use of memory-mapped files
+	 * 'C'		enable strip chopping support when reading
+	 * 'c'		disable strip chopping support
+	 * 'h'		read TIFF header only, do not load the first IFD
+	 *
+	 * The use of the 'l' and 'b' flags is strongly discouraged.
+	 * These flags are provided solely because numerous vendors,
+	 * typically on the PC, do not correctly support TIFF; they
+	 * only support the Intel little-endian byte order.  This
+	 * support is not configured by default because it supports
+	 * the violation of the TIFF spec that says that readers *MUST*
+	 * support both byte orders.  It is strongly recommended that
+	 * you not use this feature except to deal with busted apps
+	 * that write invalid TIFF.  And even in those cases you should
+	 * bang on the vendors to fix their software.
+	 *
+	 * The 'L', 'B', and 'H' flags are intended for applications
+	 * that can optimize operations on data by using a particular
+	 * bit order.  By default the library returns data in MSB2LSB
+	 * bit order for compatibiltiy with older versions of this
+	 * library.  Returning data in the bit order of the native cpu
+	 * makes the most sense but also requires applications to check
+	 * the value of the FillOrder tag; something they probably do
+	 * not do right now.
+	 *
+	 * The 'M' and 'm' flags are provided because some virtual memory
+	 * systems exhibit poor behaviour when large images are mapped.
+	 * These options permit clients to control the use of memory-mapped
+	 * files on a per-file basis.
+	 *
+	 * The 'C' and 'c' flags are provided because the library support
+	 * for chopping up large strips into multiple smaller strips is not
+	 * application-transparent and as such can cause problems.  The 'c'
+	 * option permits applications that only want to look at the tags,
+	 * for example, to get the unadulterated TIFF tag information.

+ * TIFF Library.
+ * PixarLog Compression Support
+ *
+ * Contributed by Dan McCoy.
+ *
+ * PixarLog film support uses the TIFF library to store companded
+ * 11 bit values into a tiff file, which are compressed using the 
+ * zip compressor.  
+ *
+ * The codec can take as input and produce as output 32-bit IEEE float values 
+ * as well as 16-bit or 8-bit unsigned integer values.
+ *
+ * On writing any of the above are converted into the internal
+ * 11-bit log format.   In the case of  8 and 16 bit values, the
+ * input is assumed to be unsigned linear color values that represent
+ * the range 0-1.  In the case of IEEE values, the 0-1 range is assumed to
+ * be the normal linear color range, in addition over 1 values are
+ * accepted up to a value of about 25.0 to encode "hot" hightlights and such.
+ * The encoding is lossless for 8-bit values, slightly lossy for the
+ * other bit depths.  The actual color precision should be better
+ * than the human eye can perceive with extra room to allow for
+ * error introduced by further image computation.  As with any quantized
+ * color format, it is possible to perform image calculations which
+ * expose the quantization error. This format should certainly be less 
+ * susceptable to such errors than standard 8-bit encodings, but more
+ * susceptable than straight 16-bit or 32-bit encodings.
+ *
+ * On reading the internal format is converted to the desired output format.
+ * The program can request which format it desires by setting the internal
+ * pseudo tag TIFFTAG_PIXARLOGDATAFMT to one of these possible values:
+ *  PIXARLOGDATAFMT_FLOAT     = provide IEEE float values.
+ *  PIXARLOGDATAFMT_16BIT     = provide unsigned 16-bit integer values
+ *  PIXARLOGDATAFMT_8BIT      = provide unsigned 8-bit integer values
+ *
+ * alternately PIXARLOGDATAFMT_8BITABGR provides unsigned 8-bit integer
+ * values with the difference that if there are exactly three or four channels
+ * (rgb or rgba) it swaps the channel order (bgr or abgr).
+ *
+ * PIXARLOGDATAFMT_11BITLOG provides the internal encoding directly
+ * packed in 16-bit values.   However no tools are supplied for interpreting
+ * these values.
+ *
+ * "hot" (over 1.0) areas written in floating point get clamped to
+ * 1.0 in the integer data types.
+ *
+ * When the file is closed after writing, the bit depth and sample format
+ * are set always to appear as if 8-bit data has been written into it.
+ * That way a naive program unaware of the particulars of the encoding
+ * gets the format it is most likely able to handle.
+ *
+ * The codec does it's own horizontal differencing step on the coded
+ * values so the libraries predictor stuff should be turned off.
+ * The codec also handle byte swapping the encoded values as necessary
+ * since the library does not have the information necessary
+ * to know the bit depth of the raw unencoded buffer.
