            Bug ID: 256318
           Summary: [GPU Process][Filters] Make SVGFilter a
                    RenderingResource
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Layout and Rendering

This will allow caching the SVGFilter in GPU Process and will allow referencing it in DisplayList items by its RenderingResourceIdentifier. To do that RenderingResource has to not be a RefCounted. SVGFilter inherits FilterFunction which is a RefCounted. NativeImage, Gradient, DecomposeGlyphs and SVGFilter have to handle the ref-counted separate from RenderingResource.
