title: SVG/XAML: Defining a path which looks like an arrow
body: <p>I'm trying to use SVG (really XAML) to define a path which looks like a downwards pointing arrow.</p>
  
  <pre><code>   |
     |
  \  |  /
   \ | /
    \ /
     `
  </code></pre>
  
  <p>It is super-important that the edge of the arrow is sharp. I have tried with various combinations of <code>M</code>, <code>L</code> and <code>z</code> with no success.</p>
