title: How to use the bigger jQuery icons
body: <p><a href="https://stackoverflow.com/a/5262390/754439">This answer</a> explains that the jQuery team announced to roll out new icons for their UI components, but I can not find any examples of usage or even where to download them from. Additionally, all the themes in the ThemeRoller seem to offer only icons with the default size.</p>
  
  <p>What is the correct usage of those larger icon sets (if they were officially rolled out and can be easily used at all)?</p>
