title: Tile Load Events
shortdesc: Example using tile load events.
docs: >
  Image tile sources fire events related to tile loading.  You can
  listen for <code>tileloadstart</code>, <code>tileloadend</code>,
  and <code>tileloaderror</code> type events to monitor tile loading
  progress.  This example registers listeners for these events and
  renders a tile loading progress bar at the bottom of the map.</p>
