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:
  Fixes QPen dash offset for OpenGL paint engines (1.x & 2.x).
  Support multisampled pbuffers under Windows.
  tst_qpixmapfilter:  Fix compilation in namespace
  qtextcodec_symbian: Add few aliases
  Give a warning in QPixmap::handle() if pixmap is not X11 class.
  Make QStaticText honor QPainter::pen() for rich text on X11 w/raster
  Fixed compilation of MeeGo graphics system without eglext.h
  Fixed memory corruption issue in qt_blurImage for Indexed8 images.
