    <h2>Description</h2>
    <p>This test if movementX/Y can provide the change in position of the pointer, as if movementX/Y = eNow.screenX/Y-ePrevious.screenX/Y</p>

    <h2>Manual Test Steps:</h2>
    <p>
        <ol>
            <li>Click to start Test1.</li>
            <li>Move the mouse within the window, slow and fast, like a scribble.</li>
            <li>Click again to end test.</li>
