        Repaints inside of an SVGImage were thrown on the floor,
        which broke incremental painting due to loading, or SVG animation.
        Fix this by assigning the SVGImage a ChromeClient subclass that passes
        along repaints via a new method on ImageObserver, which also takes
        a rect parameter for the changed rect, allowing incremental repaints.
        Fix RenderImage::imageChanged to take advantage of this changedRect to
        only repaint the changed parts of the image.
