We can scale the canvas itself with CSS if we want them to be any larger or smaller than that.

In principle this is a much more sensible way of doing things, since it eliminates the arithmetic around
cellSizeand probably makes the scrolling less CPU-intensive (#10) because we’re not copying as much image data. This technique might also make it easier to customise the page for mobile devices (#29).In practice it’s not ready because scaling the
<canvas>with CSS makes it blurry — browsers use bilinear interpolation or similar to resample scaled images, rather than causing pixelation with nearest-neighbour, but we want pixelation in this case. I’ve tried various fixes (e.g. CSS 3’simage-renderingproperty) but none of them seem to work, at least in Chrome.Can anyone make this work?
