A version of [[Reference_ranges_for_blood_tests]] attempted to replace a PNG of a large panoramic graph (4436x400 pixels) with an SVG -- [[Image:Reference_ranges_for_blood_tests_-_by_mass.svg]].
In theory, this should look nice... but our SVG rasterization limit of 2048x2048 hits it, so it gets rendered to 2048x185 and scaled up in-browser... which looks terrible. :)
We don't want to render things super-huge, but for panoramic-style images, it shouldn't be terribly expensive. The limit should probably be changed to work on area, like our existing restrictions on PNG resizing.
