+ * img: Add back support for SVG images, bypassing ImageMagick and
+ simply passing the SVG through to the browser, which is supported by all
+ commonly used browsers these days.
+ SVG scaling by img directives has subtly changed; where before
+ size=wxh would preserve aspect ratio, this cannot be done when passing
+ them through and so specifying both a width and height can change
+ the SVG's aspect ratio.
