title: How can I disable scaling points of canvas elements using fabric.js?
body: <p>By default fabric.js elements come with 8 points to scale any objects. But the app I'm working specifically requires that stretching should not be allowed on a single axis (horizontally or vertically). 
  I only want the corner points, not the ones on sides.</p>
  
  <p>Is it that possible with fabric.js?</p>
