Merge branch 'qt-master-from-4.7' of scm.dev.nokia.troll.no:qt/qt-integration into master-integration
* 'qt-master-from-4.7' of scm.dev.nokia.troll.no:qt/qt-integration: (237 commits) Fix animation tests after merge Remove duplicated test. Add missing test file. Changing width of RTL positioner doesn't relayout Fix TextInput auto test failure on mac. PinchArea and Flickable don't work well enough together Do not set focus unnecessarily at window activation in Symbian QS60Style: Regression in drawing dialog background QS60Style: Support menu separator (pt.2) Fix auto test failure. Support for new softkey in Symbian^3 Once Image sourceSize is set there is no way to clear it. Rotation transform with NaN angle can cause crash QSoftkeyManager auto test update Fixed not switching to MeeGo graphicssystem. Canceling image download while reading causes crash Fix width of TextInput micro focus rectangle. Return correct boundaries reasons from QTextBoundaryFinder. GridView jumps to beginning of list when resized Fixed rounding of coordinates pre-transformation in CG paintengine. ...
