One other equivalent simplification: if these images are all *just* being used as images (i.e. we're not having the user view them directly in a tab), we can just drop the `viewBox` attribute.

Specifically for SVG-as-an-image: when we see `<svg width="someWidth" height="someHeight">` with unspecified viewBox and preserveAspectRatio, all browsers *automatically synthesize* a viewBox with position `0 0 someWidth someHeight` and with `preserveAspectRatio="none"`.

So: if that's the behavior you want (and typically it is, if you're trying to make something that's analogous to a raster image but just scales more crisply), then the simplest approach is just to omit the `viewBox` and `preserveAspectRatio` attributes.

But if viewBox and/or preserveAspectRatio are provided, then something more subtle will happen.

In this case it seems like we want those synthesized attribute values, so we can just drop the viewBox to get them automatically and to avoid repeating ourselves (repeating the SVG dimensions in the hardcoded viewBox).
