title: add swipe effect for the jquery fancybox lightbox
body: <p>Fancybox has a full support and works fine on desktop platforms, however mobile/touch devices don't support the <code>:hover</code>  state property therefore, if displaying a fancybox gallery like :</p>
  
  <pre><code>&lt;a class="fancybox" rel="gallery" href="image01.jpg"&gt;01&lt;/a&gt;
  &lt;a class="fancybox" rel="gallery" href="image02.jpg"&gt;02&lt;/a&gt;
  &lt;a class="fancybox" rel="gallery" href="image03.jpg"&gt;03&lt;/a&gt;
  ... etc.
  </code></pre>
  
  <p>and this simple code :</p>
  
  <pre><code>$(".fancybox").fancybox();
  </code></pre>
  
  <p>fancybox navigation arrows would need a <em>double-click</em> to move to the next item, one to show the navigation arrow (<code>:hover</code>) and other to actually advance to the next/prev item.</p>
  
  <p>The question is : does fancybox have a swipe functionality for ipad, iphone etc. ? If not, how it can be implemented using jQuery?</p>
