  Doc
  Remove unsupported plugin version flags in .pro files of declarative examples
  Documentation typo.
  More QML doc consistency.
  Ensure existing image is gone before next photo selection.
  Don't use zoomfactor.
  Doc: in QML use "real" and "enumeration", not "qreal" and "enum"
  Doc: Put "default" property label on same line as property name
  Wait for debug clients asynchronously instead of blocking creation of
  Test not reliable
  ResizeMode support for QGraphicsWidgets created with QDeclarativeView
  More class documentation fixes for declarative.
