WebGL canvas scaled with CSS, on Safari, Chrome and Firefox
WebGL canvases seem to ignore the CSS "image-rendering:-webkit-optimize-contrast;" rule, and always render blurry when scaled up. Here is a demo:

This page displays how I would expect it to in Firefox -- all the pixels are crisp as they should be. Chrome seems to have the same issue as Safari. See screenshot for a comparison of all three browsers.
