    Description

      PinchHandler doesn't respect minimum/maximumScale.

      Code sample:

      import QtQuick

Window {
    width: 640
    height: 480
    visible: true

    Rectangle {
        id: redRect
        anchors.centerIn: parent
        width: 200
        height: 200
        color: 'red'

        Text {
            anchors.centerIn: parent
            font.pixelSize: 18
            text: parent.scale.toFixed(2)
        }
    }

    PinchHandler {
        target: redRect
        minimumScale: 0.5
        maximumScale: 1.5
    }
}
