title: whole viewgroup to bitmap
body: <p>Is it possible to get a full bitmap from a viewgroup-object?</p>
  
  <p>This code takes a 'screenshot' off the view group that's currently on the screen, but I want the whole view, also what's not currently on the screen.</p>
  
  <pre><code>public void export(ViewGroup view){
      view.setDrawingCacheEnabled(true);
      view.setDrawingCacheQuality(View.DRAWING_CACHE_QUALITY_HIGH);
      Bitmap bitmap = view.getDrawingCache(true);
  }
  </code></pre>
