Browser scaling is also at least worth
experimenting with. Instances where browser scaling would be bad are
likely instances where the image is already subpar if viewed on a high-dpi
/ retina display.
Other instances where browser scaling is bad are:
* PoS browsers that don't render SVGs (how old are these by now?)
* Even modern browsers have subpar SVG rendering at 1x, PNG looks better
* Some media types are "scaled" in unusual ways (SVGs, but also video
stills, PDF pages, ...)
* Some original images are really friggin' large (20-30 megapixels
sometimes), so at least some downscaling is needed there
* Mobile clients will want to minimize the amount of data transferred
