SVG filters on HTML content is a bad time
Right now we fallback to BasicLayerManager which isn't going to be a good time. Unfortunately, we're the only browser that supports SVG filters on HTML content.
Actually, Chrome and Safari support it as well.
This is a regression for Windows users because BasicLayerManager with Direct2D was at least hardware accelerated. With WebRender we disable Direct2D, so filters run on the CPU. It's also a regression for everyone because we don't have good invalidation support in the WebRender fallback code, so we always repaint the entire filter if anything inside it changes.
