// Because PaintLayer is not allocated for SVG objects, SVG filters (both
// software and hardware-accelerated) use a different code path to paint the
// filters (SVGFilterPainter), but both code paths use the same abstraction for
// painting non-hardware accelerated filters (FilterEffect). Hardware
// accelerated CSS filters use CompositorFilterOperations, that is backed by cc.
