  Cocoa, Autotest: disable autotest that was added a bit premature
  make error messages consistent
  Add tests/benchmarks/README
  qgrayraster: Remove unnecessary indirection in QT_FT_Outline_Decompose
  Cocoa: add autotest to be more safe regarding child window stacking
  Fix compilation: QT_NO_TEXTSTREAM
  exclude QtXmlPatterns from the completeness assessment
  fix QMAKE_SUBSTITUTES with shadow builds
  Outline / fill inconsistency in X11 paint engine.
  Cocoa: parent windows shows on screen when they should be hidden
  Prevented Xorg crash in qtdemo when running corkboards example.
