Make sure a container size is always set for SVG images in <svg:image>
If a referenced image had the same dimensions as the referencing <image>,
a container size would not be set. This could cause the wrong scaling (etc)
to be applied if there existed another reference to the same image resource
that ended up applying a different scale-factor.
To ensure that a container size is set in this case, determine if the
referenced image has a container size set or not by checking if what
the "base" image (as returned by ImageResource::image()) differs from the
RenderObject-specific image (as returned by
ImageResource::imageForRenderer)
