title: Trigger or Force Redraw or Re-Render of WebView
body: <p>My understanding is that WebView's <code>PictureListener.onNewPicture()</code> is called whenever the already loaded page finished rendering (or re-rendering in case certain events make the WebKit engine re-calculate page layout).</p>
  
  <p>I also (think that I) understand that those WebView renders are controlled internally in WebView and ordinarily I wouldn't care how they are being generated.</p>
  
  <p>However, for a certain function in my app, I need to trigger an extra <code>PictureListener.onNewPicture()</code> <strong>without</strong> re-loading the url (i.e. no <code>reload()</code> or <code>loadUrl()</code>).</p>
  
  <p>Essentially, what I am looking for is a function like repaint() or redraw() or some other mechanism that only generate one more <code>PictureListener.onNewPicture()</code> and that's it (without the slowness and overhead associated with re-loading data).</p>
  
  <p>Is there a way to achieve this?</p>
