Detailed Description

GPU filter-graph executor for the Geode rendering backend.

Owns compute pipelines for filter primitives and executes a donner::svg::components::FilterGraph against a source-graphic texture, returning the filtered output texture.

Implemented primitives: feGaussianBlur, feOffset, feColorMatrix, feFlood, feMerge, feComposite, feBlend, feMorphology, feComponentTransfer, feConvolveMatrix, feTurbulence, feDisplacementMap, feDiffuseLighting, feSpecularLighting, feDropShadow, feImage, feTile. The primitive visitor is exhaustive.
