title: On the fabricjs how can you determine if an object already exists at certain coordinates?
body: <p>I have been working with fabricjs for the last few weeks and I cannot find a solution for an issue I am having.
  I have an object and I would like to programmatically determine if the area around it is "empty" (there are no objects ), so if I would add an object there they would not intersect.</p>
  
  <p>I have been playing around with canvas.findTarget and different "virtual" objects but I cannot get anything to work.</p>
  
  <p>This is a solution I found:</p>
  
  <pre><code>var targetPoint = new fabric.Point(target.left + offset + 1, target.top + 1);
            if (obj.containsPoint(targetPoint)) {
              objectOnRight = obj;
            }
  </code></pre>
  
  <p>Best regards,
  Alex</p>
