title: Put text on animated GIF and save it as a new GIF
body: <p>I'm looking for a function that could process animated gif image to write text on top of it. </p>
  
  <p>The working solution is probably provided by Gif4j lib, but I'm looking for open-source solution or advice how to implement it on my own. </p>
  
  <p>How can I put text on a gif and save it as a new gif in Java?</p>
