  Accept enter key in the webbrower demo url input.
  Keep reported point/pixel size in sync.
  Remove unnecessary CloseSoftwareInputPanel events after TextEdit or TextInput has lost focus
  Ensure state operations assigned to the default state are triggered
  Add image example.
  Fix regression in input panel autotests
  Improve docs about Qml component case sensitivity.
  Add some performance tips to QML docs.
  Move QListModelInterface into util.
  Ensure ParticleMotionGravity always pulls in the right direction.
  Remove version ifdefs from Particles; only 4.7 is supported.
  Update docs for the runtime.orientation values
  Revert to Portrait/Landscape terminology for Orientation enum, with
  Add more Q_AUTOTEST_EXPORTs
  Improve input panel handling in declarative demos and examples
  Always integer align anchor center points
  Add header and footer to GridView
