title: Draw border edges of the Konvajs container Stage in html
body: <p>I am using the Konvajs library. Am trying to put a border box around the main <code>Stage</code> element, but can't seem to make it work. The CSS only apply to the <code>&lt;div&gt;</code> and the <code>Konva.Stage</code> element does not seem to have specific properties for this.</p>
  
  <p>Is the only way to add line shapes on the 4 borders of the Stage Layer?</p>
  
  <p>My Konva container</p>
  
  <pre><code>&lt;div class="TSPKonvaStage" id="KonvaContainer"&gt;&lt;/div&gt;
  </code></pre>
  
  <p>My Konva Declaration below</p>
  
  <pre><code>var stage = new Konva.Stage({
          container: 'KonvaContainer',   // id of container &lt;div&gt;
          width: 600,
          height: 180
       });
  </code></pre>
