RazrFalcon has just created a new issue for https://github.com/w3c/svgwg: == What is the purpose of BackgroundImage filter input in SVG 2? == https://www.w3.org/TR/filter-effects-1/#attr-valuedef-in-backgroundimage In SVG 1, `BackgroundImage` was used in tandem with `enable-background` to render part of SVG into a filter input buffer. In SVG 2, there are no `enable-background` anymore (no one really supported it anyway) and the spec simply says: >This keyword represents the back drop defined by the current isolation group behind the filter region at the time that the filter element was invoked. See isolation property. But the `filter` attribute always forces group isolation, meaning it the same as using `SourceGraphic`, no? And browsers do not support it either. Chrome does handle `BackgroundImage` sometimes (probably simply fallbacks to `SourceGraphic`), but not `BackgroundAlpha`. What is the difference between `SourceGraphic` and `BackgroundImage` in terms of SVG 2?
