  You can also combine this plugin with the jQuery UI built-in resizable() and draggable(), although the latter works best when applied to a container with the rotatable inside it. See the Demo page for some examples.

  // Assign Draggable
  $('.box-wrapper').draggable({

  // Assign Rotatable

  // Assign coordinate classes to handles
