title: Is there a way to get the current Stroke on an InkCanvas?
body: <p>In UWP I am using an <code>InkCanvas</code> to detect strokes. I would like to change the color of the current <code>Stroke</code>.
  I tried a couple of events but I'm only able to change the color of the <code>Stroke</code> after it has been collected through the following event:</p>
  
  <pre><code>InkCanvas.InkPresenter.StrokesCollected += InkPresenter_StrokesCollected
  
  private void InkPresenter_StrokesCollected(InkPresenter sender, InkStrokesCollectedEventArgs args)
  {
      foreach (InkStroke stroke in InkCanvas.InkPresenter.StrokeContainer.GetStrokes())
      {
          InkDrawingAttributes drawingAttributes = new InkDrawingAttributes();
          drawingAttributes.Color = Windows.UI.Colors.Blue;
          stroke.DrawingAttributes = drawingAttributes;
      }
  }
  </code></pre>
  
  <p>I also tried the events on <code>StrokeInput</code> but I'm unable to find the current Stroke this way.</p>
