If you're on desktop, you can now zoom in and out on the grid with the [ and ] keys.

I'd previously toyed with animations that would zoom in and out when navigating far distances on the grid, but never settled on one that I liked. This feature takes inspiration from that, letting you just zoom in and out as you please.

At 3 levels of zoom, the performance of the page is a little janky, but not so bad that I want to do further rendering improvements (above and beyond the switch from position offsets to css transforms in this commit).
