Use SVGs for identity graphics?

[akx]

On HiDPI displays, text is lovely and crisp, but graphics such as the logo and the event name in the header are a bit on the blurry side.

Using SVGs (or failing that, HiDPI raster images) would help with that. (I would've contributed a PR, but I noticed the logos are packed into a spritesheet, so it wasn't as trivial as I'd hoped... 😄)
