title: Fill in empty space between a curved line
body: <p>I have the following line:</p>
  <pre><code>    canvas.create_line(25,25,75,25,50,50, smooth = True)
  </code></pre>
  <p>That creates the following line:

  <p>Let's say I then wanted to fill the space in between the line with white. Something like this would be the desired result:

  <p>How would I go about doing this?</p>
