I want SVGs in img elements to load external fonts

Translating graphics is a pain. Currently if you want to use img elements with SVGs, you lose the ability to load external fonts inside of the SVG. You can embed the fonts in the CSS inside of the SVG but that means that the font is downloaded every time a SVG is requested.
Allowing us to embed fonts in SVGs used in the img element would make the web a more accessible and multilingual-friendly page.
