title: Make Exoplayer Closed Captions (CEA-608) appear at the bottom
body: <p>how can I make Exoplayer Closed Captions (CEA-608) appear at the bottom like the regular subtitles? Now they appear at the place on screen where character talks.
  I tried:</p>
  
  <pre><code>exoView.getSubtitleView().setTextAlignment(View.TEXT_ALIGNMENT_CENTER); 
  </code></pre>
  
  <p>But it is not working.
  I need them to appear at the bottom.
  SubtitleView is regular View, maybe there are some methods for that? I haven't found, please help!</p>
