[Interest] MouseArea failed to handle onPositionChanged to a frameless ApplicationWindow in Qt 5.2.1

[Leslie Zhai]

Hi qt developers,

I use MouseArea to act like DragArea to move the frameless 
ApplicationWindow in Qt5.2.1 
https://github.com/AOSC-Dev/QJade/blob/master/qml/DragArea.qml#L17

But Window Cannot Be Moved Over the Borders the Screen
