Is it possible to generate a box-shadow that follows the shape of a clip-path polygon?
<p>Let's say I have this clip path (a triangle generated <a href="http://bennettfeely.com/clippy/" rel="noreferrer">here</a>)</p>

<pre><code>-webkit-clip-path: polygon(50% 0%, 0% 100%, 100% 100%);
clip-path: polygon(50% 0%, 0% 100%, 100% 100%);
</code></pre>

<p>Is it possible to create a box-shadow from this clip path?
Something like this:</p>

<pre><code>box-shadow: 20px 25px 50px -25px #000;
</code></pre>
