title: How to use a proxy with html2canvas (latest version)
body: <p>I'm trying to capture a screenshot of a bing map with html2canvas. From what I can see I need to use a proxy to allow external images to be captured. <a href="https://github.com/niklasvh/html2canvas/blob/master/docs/proxy.md" rel="nofollow noreferrer">I see this suggested use.</a> But I really don't see any suggestion on how it could be used (like an example). Anyone have an example? I'm using the latest version with promises. Thanks!</p>
