Как растянуть SVG в качестве полноэкранного фона ⇐ CSS

[Anonymous]

Я хочу использовать свой SVG в качестве фона моей веб-страницы, выровненной вверху справа, но я не нашел способа добиться этого даже в качестве фонового изображения с помощью CSS.
Вот JSFiddle, где вы можете видеть, что мой SVG автоматически центрируется, когда я хочу, чтобы он был справа: https://jsfiddle.net/kodjoe/gsvyhm07/11/
Обратите внимание, что я хочу сохранить соотношение SVG.
