Qt3D color handling out of date

The following example demonstrates. Both hslLightness and Qt.hsva() cease to function correctly once the Qt3D import is included.

import QtQuick 2.0
//import Qt3D.Core 2.0 // uncomment to see errors

Item {
    property color myColor: "red"

    Component.onCompleted: {
        console.log(myColor.hslLightness)
        myColor = Qt.hsva(1,0,1,1)
    }
}

The Qt3D color handling code should be updated to match the latest QtQuick code, so behavior is identical.
