      Description

      MultiPointTouchArea generates two "Released" events when used with a mouse. When used with a touch screen, only one released event is generated. The code below generates the following output when used with a mouse:

      qmlscene.exe main.qml
      qml: QML Pressed QQuickTouchPoint(0x4ef3300)
      qml: QML Released QQuickTouchPoint(0x4ef3300)
      qml: QML Released QQuickTouchPoint(0x4ef3300),QQuickTouchPoint(0x4ef3300)

      When used with a touch screen:

      qmlscene.exe main.qml
      qml: QML Pressed QQuickTouchPoint(0x6433630)
      qml: QML Released QQuickTouchPoint(0x6433630)

      import QtQuick 2.2
      import QtQuick.Controls 1.1
      
      ApplicationWindow {
          visible: true
          width: 640
          height: 480
          title: qsTr("Hello World")
      
          MultiPointTouchArea {
              anchors.fill: parent
              onPressed: {
                  console.log("QML Pressed " + touchPoints)
              }
      
              onReleased: {
                  console.log("QML Released " + touchPoints)
              }
          }
      }
