title: Adding a Mask Overlay on top of Leaflet v0.8-dev
body: <p>I'm trying to create a circular masked overlay using Leaflet 0.8 that is positioned over the users currently location, extending a radius of 1000 meters. Essentially making the map visible around the user (as a circle), and grayed out beyond 1000 meters</p>
  
  <p><strong>Mockup:</strong></p>
  
  <p><img src="https://i.stack.imgur.com/Dv8G6.png" alt="http://i.stack.imgur.com/Dv8G6.png"></p>
  
  <p>As the user zooms in/out on the map, the circle should resize accordingly. </p>
  
  <p>I tried using <strong><a href="https://github.com/domoritz/leaflet-maskcanvas" rel="nofollow noreferrer">leaflet-maskcanvas</a></strong>, a plugin for Leaflet that looks like it would do exactly what I need, unfortunately with all refactoring done in Leaflet 0.8-dev, this plugin isn't compatible.</p>
  
  <p>Has anyone been able to achieve this effect successfully with Leaflet 0.8?  </p>
