Thread:Extension talk:Score/Retina/high-density display support needed

I notice that this renders to raster PNG files at traditional 1.0x screen resolution.

There's more and more devices with higher-res screens coming to market (iPhone, iPad, many Android phones, laptops from Apple, Google, and soon Toshiba) and it'd be awesome if score output looked clean on those displays.

Since SVGs aren't available yet and we probably don't want to embed PDFs :)... the simplest solution would be to render PNGs at 1.0 (current), 1.5, and 2.0 scales, and use the 'srcset' attribute to list the 1.5x and 2.0x variants. This will be picked up at runtime by our JavaScript code (or, in the future, interpreted directly by the browser) to load up the larger versions when viewed on an appropriate screen.
