title: ViewPager setCurrentItem(pageId, true) does NOT smoothscroll
body: <p>I am compiling on SDK 4.03, Samsung Infuse Android 2.2, Support Library for Android 4,  and using ViewPager in my app, actual swipe works fine, but when I do </p>
  
  <pre><code>viewPager.setCurrentItem(id); // , or
  viewPager.setCurrentItem(id, true);  
  </code></pre>
  
  <p>It does not smooth scroll, but switches views instantly.  Although the documentation clearly states that that is the purpose setting the second argument to true.  Whats up with this?</p>
