Subject: Fix issues with thai line breaking
Merge latest harfbuzz:
commit cce760d41f115fecd5b9b6b20b62883b10a9c204
Author: Lars Knoll <lars.knoll@nokia.com>
Date: Mon Jun 14 14:14:59 2010 +0200
Fixes for thai linebreaking
* Load libthai.so.0 since libthai.so is not there on all systems
* Remove dependency on codecs. Unicode->TIS620 is so simple we can
simply hardcode it in harbuzz-thai.c
* Speed up detection of word boundaries
* Falback when libthai is not found is now to not break instead of
breaking after every character (in line with recommendations from
unicode.org linebreaking algorithm)

+Qt 4.6.4 is a bug-fix release. It maintains both forward and backward
+compatibility (source and binary) with Qt 4.6.0. For more details,
+refer to the online documentation included in this distribution. The
+documentation is also available online:
+
+ http://qt.nokia.com/doc/4.6
+
+The Qt version 4.6 series is binary compatible with the 4.5.x series.
+Applications compiled for 4.5 will continue to run with 4.6.
+
+Some of the changes listed in this file include issue tracking numbers
+corresponding to tasks in the Qt Bug Tracker or the Merge Request queue
+of the public source repository.

+ Make GIFs loop the correct number of times. Previously, everyone looped
+ one time too few for non-infinitely-looping GIFs.
+
+ Modified a Qt manual test to be correct and moved it to the general
+ manual test directory.

+ * manual-tests/animated-gif-looping.html: Copied from WebCore/manual-tests/qt/qt-gif-test.html.
+ * manual-tests/qt/qt-10loop-anim.gif: Removed.

+ * platform/graphics/qt/ImageDecoderQt.cpp:
+ (WebCore::ImageDecoderQt::repetitionCount): Remove translation code now that WebCore matches Qt's internal handling of the loop count. Qt itself may still have a bug here.

+ (WebCore::GIFImageDecoder::repetitionCount):
+ * platform/image-decoders/gif/GIFImageReader.cpp:
+ (GIFImageReader::read): Translate loop count 0 to "loop infinitely" (by restoring one piece of the Mozilla code we'd removed).

+// * By making cAnimationLoopOnce be 0, we allow the animation cycling code in
+// BitmapImage.cpp to avoid special-casing it, and simply treat all
