title: html canvas shape blur filter
body: <p>There must be a way to do this. I have drawn a shape with the html5 canvas and I would like to blur it. As far as I know there is no native method so I assume a js library is needed. The problem is most libraries only blur images like <a href="http://www.pixastic.com/lib/docs/actions/blur/" rel="noreferrer">this</a> one for example. Is this possible?</p>
