title: Setting Control Visibility for Drawn Objects
body: <p>I have a <code>fabricjs</code> canvas with a button that toggles drawing on and off. How can I apply the custom controls to any/all drawn objects that I draw; for example, I'd like to select any of the lines that I draw and only be able to rotate them. I've read <a href="http://fabricjs.com/controls-customization" rel="nofollow noreferrer">the example</a> but must be missing something. How would I accomplish this?</p>
