Merge branch '4.6' of scm.dev.nokia.troll.no:qt/oslo-staging-2 into 4.6-integration
* '4.6' of scm.dev.nokia.troll.no:qt/oslo-staging-2: (21 commits) Fixed a failure in tst_qgl. 4.6.2 changes Avoids a possible crash when saving the state of a main window Implemented QGifHandler::imageCount(). Fixed compilation of the GL2 engine for OpenGL ES 2. fix whitespace Document that QModelIndex::child does not work for the root item Fixed missing textures in the boxes demo. Fix QTBUG_7714_fullUpdateDiscardingOpacityUpdate2 autotest in qws-linux Assert failure when setting a widget focus proxy as its successor in tab order Fixed garbled 3D Qt logo in the overpainting example. fix crash in Phonon::DS9 backend Don't crash when running Qt on KDE with Oxygen style. Fixes missing update when setting opacity on an item that had opacity 0.0 Avoids missing opacity updates by not propagating the ignoreOpacity flag Cleanup in graphicsitem autotest Adds convenience functions QGraphicsItemPrivate::isOpacityNull Fixed a crash when QPixmaps are destroyed after the ~QApplication. Fix GL texture leaks when pixmaps are deleted Doc fix. No need to put something deprecated if it's not. ...
