title: Blur text in TextView unexpected behaviour
body: <p>I'm trying to blur text in a TextView using setMaskFilter, the behavior seems unexpected, upper case chars, and new line, are not getting blurred, what's wrong with the below?</p>
  
  <pre><code>                textView.setText(feed.getText());
                  BlurMaskFilter.Blur style = BlurMaskFilter.Blur.NORMAL ;
  
                  float radius = textView.getTextSize() ;
                  BlurMaskFilter filter = new BlurMaskFilter(radius, style);
                  textView.getPaint().setMaskFilter(filter);
                  //The text is blurred here but Bes are not 
                  textView.setText("Blah blah Blah blah");
                  //This is blurred completely 
                  textView.setText("blah blah blah blah");
  </code></pre>
