title: Canvas to blob support in IE 11
body: <p>I am using react-image-crop (<a href="https://github.com/DominicTobias/react-image-crop" rel="nofollow noreferrer">https://github.com/DominicTobias/react-image-crop</a>) within my react app to crop images:</p>
  
  <p>I know that IE 11 does not support <code>toBlob</code> and was trying to use this polyfill: <a href="https://github.com/eligrey/canvas-toBlob.js" rel="nofollow noreferrer">https://github.com/eligrey/canvas-toBlob.js</a></p>
  
  <p>I ran <code>yarn add canvas-toBlob</code> and then imported it into my react component as <code>import canvasToBlob from 'canvas-toBlob';</code>.  I keep getting an error: "Object doesn't support this action". Is there something else that I should be doing?</p>
  
  <p>Should I be importing the script into my main <code>index.html</code>?</p>
