title: filesaver.js not working iPad Chrome
body: <p>I'm trying out Eli Grey's awesome filesaver implementation to download canvases as a PNG image.</p>
  
  <p>It's working well on most platforms, but I've hit a snag on Chrome on the iPad - it just opens a new tab that remains blank.</p>
  
  <p>I do have a fallback for browsers that can't handle blobs, so I'm hoping there's some feature detection I can do to recognise when I might need to use the fallback.</p>
  
  <p>Any suggestions?</p>
