Added a new QXYSeries::replace override for performance reasons....
Added a new QXYSeries::replace override for performance reasons. Also added a QML demo application for oscilloscope use case. Oscilloscope use case was selected, because it involves a lot of data and has a strict requirements for performance. It revealed performance issues in data handling in QXYSeries, painting of QLineSeries and updating data in a model.
