Re: [svgwg] [svg-native] Limited support for filters? (#675)

Yes, if supported at all it should just be a set of filter functions.

As said, before, filters require an implicitly or explicitly created off-screen buffer to perform.

* On macOS/iOS there is CoreAnimation and CoreImage that support filters, CoreGraphics _does not_ (with the exception of shadow).
* Skia _does_ have a set of filters that are similarly implemented in Qt, D2D and GDI+ (blur, hue-rotate, contrast, brightness).
* Cairo graphics _does not_ support filter effects.
