    Description

      In QQuickPinchHandler::handlePointerEventImpl(), we have this in the else block for when the event is not a native gesture:

              m_activeScale = qBound(m_minimumScale/m_startScale, m_activeScale, m_maximumScale/m_startScale);

      but no similar use of those min/max values when it's a native gesture. So you can scale things infinitely with a touchpad that sends those events, regardless of limits.
