{QTouchEvent,QWindowSystemInterface}::TouchPoint: replace QList<QPointF> with QVector

Browse Source 
QPointF is in the category of types for which QList
is needlessly inefficient (elements are copy-constructed
onto the heap and held through pointers). Use a vector
instead. This is consistent with the QPainter API.

Returns the raw, unfiltered positions for the touch point. The positions are in native screen coordinates.
To get local coordinates you can use mapFromGlobal() of the QWindow returned by QTouchEvent::window().
\note Returns an empty list if the touch device's capabilities do not include QTouchDevice::RawPositions.
\note Returns an empty vector if the touch device's capabilities do not include QTouchDevice::RawPositions.
\note Native screen coordinates refer to the native orientation of the screen which, in case of
mobile devices, is typically portrait. This means that on systems capable of screen orientation
