Merge branch '4.7' of scm.dev.nokia.troll.no:qt/oslo-staging-2 into 4.7-integration
* '4.7' of scm.dev.nokia.troll.no:qt/oslo-staging-2: (60 commits) Total makeover of SVG image reader Add a QGraphicsItem::updateMicroFocus() to QGraphicsItem. Micro optimization after feedback from Jan-Arve. Show only one dialog when using QFileDialog on Mac. Re-fix compilation: re-add symbols introduced in Qt 4.6.3 to Qt 4.7 Fix bad merge from 4.6. Doc: Updated the qdoc manual with i18n info. Fixed a code example. Fix QStaticText test on Mac Support the pen set on the painter in QStaticText when using rich text Fix setting font for QStaticText on Linux and Mac Hack .pro files on windows to define QT_NO_EGL Fix QDate::isLeapYear() for years < 1 One more test for chinese codecs QScript: More missing APIShim QScriptEngine: Fix reentrency involving creation and desctructions of QScriptEngines Work-around Symbian 10.1's broken egl.h Add some #warnings to debug Symbian EGL build failure Don't detect EGLImage presence by testing function pointers Implement proper QStaticText support in QPaintBuffer Make QStaticText layout lazy ...
