title: Easeljs rotate object using mousemove
body: <p><em>I'm working in HTML5 canvas + Easeljs</em></p>
  
  <p>I would like to rotate objects in my application using my mouse. Idea is the following: click on an object > circle appears with draggable box > drag this box over the circle makes the object rotate.</p>
  
  <p>It is kinda the same question as <a href="https://stackoverflow.com/questions/26244982/html5-canvas-make-image-rotate-around-click-to-select-and-drag-circle">this one</a>, but I have no clue how to do this in Easeljs.</p>
  
  <p><strong>To illustrate</strong>

  <p>Now you can rotate objects by clicking the buttons in the top right (L = left, R = right), but I want it to be like here:</p>

  <p><em>Click + drag on white box will make it rotate</em></p>
  
  <p>Help is much appreciated!</p>
