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

+<A NAME="configure"><B><FONT SIZE=+3>C</FONT>HANGES IN THE SOFTWARE CONFIGURATION:</B></A>
+
+<UL>
+
+ <LI> Added GNULDdso target and switched linux and freebsd to use it.
+ <LI> tools/Makefile.in: Modified to install properly on SGI.
+ <LI> configure: Fixed DSO test for Linux as per patch from
+ Jan Van Buggenhout <chipzz@Ace.ULYSSIS.Student.KULeuven.Ac.Be>.

+
+<A NAME="libtiff"><B><FONT SIZE=+3>C</FONT>HANGES IN LIBTIFF:</B></A>
+
+
+<UL>
+
+ <LI> tif_dir.c: Clear TIFF_ISTILED flag in TIFFDefaultDirectory
+ as per http://bugzilla.remotesensing.org/show_bug.cgi?id=18
+ from vandrove@vc.cvut.cz.
+
+ <LI> Modified tif_packbits.c decoding to avoid overrunning the
+ output buffer, and to issue a warning if data needs to be
+ discarded. See http://bugzilla.remotesensing.org/show_bug.cgi?id=18
+
+ <LI> Modified TIFFClientOpen() to emit an error on an attempt to
+ open a comperessed file for update (O_RDWR/r+) access. This is
+ because the compressor/decompressor code gets very confused when
+ the mode is O_RDWR, assuming this means writing only. See
+ bug http://bugzilla.remotesensing.org/show_bug.cgi?id=13
+
+ <LI> Applied patch for 0x0000 sequences in tif_fax3.h's definition
+ of EXPAND1D() as per bug 11 (from Roman).
+
+ <LI> Fixed tiffcomp.h to avoid win32 stuff if unix #defined, to improve
+ cygwin compatibility.
+
+ <LI> Applied patch from Roman Shpount to tif_fax3.c. This seems to
+ be a proper fix to the buffer sizing problem. See
+ http://bugzilla.remotesensing.org/show_bug.cgi?id=11
+
+ <LI> Fixed tif_getimage.c to fix overrun bug with YCbCr images without
+ downsampling. http://bugzilla.remotesensing.org/show_bug.cgi?id=10
+ Thanks to Nick Lamb <njl98r@ecs.soton.ac.uk> for reporting the
+ bug and proving the patch.
+
+ <LI> Fixed tif_jpeg.c so avoid destroying the decompressor before
+ we are done access data thanks to bug report from:
+ Michael Eckstein <eckstein@gepro.cz>.
+
+ <LI> tif_open.c: Don't set MMAP for O_RDWR files.
+
+ <LI> tif_open.c: Set STRIPCHOP_DEFAULT for O_RDWR as well as O_RDONLY
+ so that files opened for update can be strip chopped too.
+
+ <LI> tif_read.c: fixed up bug with files missing rowsperstrip and
+ the strips per separation fix done a few weeks ago.
+
+ <LI> Tentatively added support for SAMPLEFORMAT_COMPLEXIEEEFP, and
+ SAMPLEFORMAT_COMPLEXINT.
+
+ <LI> index.html, bugs.html: added bugzilla info.
+
+ <LI> tif_read.c: fix subtle bug with determining the number of
+ rows for strips that are the last strip in a separation but
+ not the last strip of all in TIFFReadEncodedStrip().
+
+ <LI> Applied 16/32 bit fix to tif_fax3.c. Fix supplied by
+ Peter Skarpetis <peters@serendipity-software.com.au>
+
+ <LI> Modified tiffio.h logic with regard to including windows.h. It
+ won't include it when building with __CYGWIN__.
+
+ <LI> README: update to mention www.libtiff.org, don't list Sam's old
+ email address.
+
+ <LI> libtiff/tif_dirread.c: Don't use estimate strip byte count for
+ one tile/strip images with an offset, and byte count of zero. These
+ could be "unpopulated" images.
+
+ <LI> tif_win32.c: Applied patch to fix overreads and ovverwrites
+ caught by BoundsChecker. From Arvan Pritchard
+ <arvan.pritchard@infomatix.co.uk> (untested).
+
+ <LI> tif_getimage.c: Applied patch to silence VC6 warnings. From
+ Arvan Pritchard <arvan.pritchard@informatix.co.uk>
+
+ <LI> tif_lzw.c: Applied patch to silence VC6 warnings. From
+ Arvan Pritchard <arvan.pritchard@informatix.co.uk>
+
+ <LI> libtiff/tif_apple.c: Applied "Carbon" support patches supplied by
+ Leonard Rosenthol <leonardr@lazerware.com>. May interfere
+ with correct building on older systems. If so, please let me know.

+
+<A NAME="tools"><B><FONT SIZE=+3>C</FONT>HANGES IN THE TOOLS:</B></A>
+
+<UL>
+
+ <LI> tools/rgb2ycbcr.c: fixed output strip size to account for vertical
+ roundup if rows_per_strip not a multiple of vertical sample size.
+
+ <LI> tools/tiffsplit.c: Copy TIFFTAG_SAMPLEFORMAT.
+
+ <LI> Modified tiff2bw to ensure portions add to 100%, and that
+ white is properly recovered. See bug
