For the SVG <use> element, we want to support loading HTML documents that have a SVG element inside of it pointed to by the URL fragment. In this situation we would need to fetch and parse the entire document in SharedImageRequest (so that we can still cache the SVGs). Rename SharedImageRequest to SharedResourceRequest to make the class a little more generic for future usecases.
