Merge branch '4.7' of scm.dev.nokia.troll.no:qt/qt-qml into 4.7-integration

* '4.7' of scm.dev.nokia.troll.no:qt/qt-qml:
  Make Item::transformOriginPoint read-only
  Ensure the boundingRect() of Text is correctly calculated.
  Better defaults for MouseArea's drag.
  various doc improvements for animation elements
  fixes for dynamic object creation docs
  Change docs to show how to define enum properties
  Improve documentation on setting arbitray transform origin points
  Ensure released VisualItemModel items are removed from the scene.
  Improve QML text rendering when LCD smoothing is enabled for OS X.
