Implements the crossOrigin attribute for SVG images: The crossOrigin attribute, valid on the <image> and <feImage> elements, provides support for configuration of the Cross-Origin Resource Sharing (CORS) requests for the element's fetched data. The supported values are the same as elsewhere: "anonymous", "use-credentials", and "" (which means anonymous). https://developer.mozilla.org/en-US/docs/Web/SVG/Attribute/crossorigin https://www.w3.org/TR/SVG/embedded.html#ImageElementCrossoriginAttribute
