Re: Progress on HDR canvas prototype

Great work Chris! This is really visually compelling!

Note to all - in Chrome, Canary channel is recommended for testing since it
has the most up-to-date code, and to see all the demos on this page it's
necessary to go to about:flags and enable "Experimental web platform
features", then restart the browser.
