/*! \example demos/quick2oscilloscope \title Qt Quick 2 Oscilloscope \image demos_qmloscilloscope.png This is a reimplementation of the \l{Oscilloscope} demo in Qt Quick 2. The main difference in qml files is importing the correct version of Qt Quick: \snippet ../demos/quick2oscilloscope/qml/quick2oscilloscope/main.qml 3 \note QML_SHOW_FRAMERATE environment variable doesn't work with Qt Quick 2. From Qt 5.1.0 on, the QSG_RENDER_TIMING environment variable can be used similarly to display rendering time. */
