title: ViewPager: set a different padding for first and last page
body: <p>I already implemented a "page peek" feature for my ViewPager:</p>
  
  <pre><code>mPager.setClipToPadding(false);
  mPager.setPadding(120, 0, 120, 0);
  mPager.setPageMargin(60);
  </code></pre>
  
  <p>Doing this I am able to view a portion of the previous and next page. But first and last page show a bigger white space because there's no other page in this direction to show.</p>
  
  <p>How can I set a different padding for the first and last page?</p>
