// <mask> reference.

// If the reference is non-local this wraps an StyleFetchedImage, and a
// corresponding SVGResource that wraps the same ImageResourceContent as the
// StyleFetchedImage. If the url() has fragment that in turn references an SVG
// <mask> element this can be used to paint/generate a mask from that source.
//
// If the reference is local an SVGResource is wrapped.
