HTMLObjectElement, when implemented according to the spec, does not know the resource type specified by the 'data' attribute until after it has actually loaded (i.e. it may be an image, XML document, etc.). Currently we always use ImageLoader within HTMLObjectElement to load the object, but will need to use ResourceLoader instead to generically load data. However, ImageLoader / ImageResource have image-specific functionality that HTMLObjectElement still needs if the resource turns out to be an image. This patch will allow (only) HTMLObjectElement to convert the generic Resource to an ImageResource as needed.
