title: Why is Slick giving me this warning regarding PNG data?
body: <p>I'm getting this warning in the console: </p>
  
  <pre><code>WARN:class org.newdawn.slick.opengl.PNGImageData failed to read the data
  </code></pre>
  
  <p>After switching between png files, it seems the warning is appearing because I was using a 16 bit PNG image. Why is this? Should I ignore it and stick with 16 bit or use 8 bit?</p>
