Make the sprites not blurry on hi resolution displays

[DamianEdwards]

When playing on a 4K screen with high-dpi (200% in my case) the ships and other sprites look blurry, as the view is scaled to the browser size and the sprites are always scaled to a percentage of that, and the current sprite sizes aren't large enough to scale up to hi resolution displays.

You may be able to hack the scale of the ship side here, at 4K you will have more room to drive the ship around the screen without scaling the whole game. I would try it myself, but I cannot get it to build on my machine.
