title: Sort order of FilesystemIterator
body: <p>I want to list all the images in a specific folder using FilesystemIterator. Over time that folder will be filled with a lot images, which will of course slow the system down.</p>
  
  <p>I'm thinking about creating a pagination function, and only show for example 20 images at once. But I would like it to be sorted after the latest modified images (because this will make it easier for the user, not having to look through all the pages).</p>
  
  <p>I don't want to put the entire directory in an array and then sort it, as that would kind of beat the purpose.</p>
  
  <p>My question is, is it possible to set the sort order of FilesystemIterator?</p>
