Retina / high resolution display support

[kbirk]

Has anyone looked into adding support to render at native resolutions on retina / hi res displays?

Usually it amounts to multiplying the canvas.width and canvas.height by window.devicePixelRatio and scaling any rendered shape dimensions bywindow.devicePixelRatio.

Hello, @kbirk 👋 .

There is some initial work done in #260. The initial changes are far from perfect as they only cover the tile size problem.
