The current version of Org wraps the SVG image in a <div> of class
figure, but at least setting the width of this class in a CSS produces
no scaling effect (tested with Chrome and Safari).

But if you need to set an id, then you will also have to do scaling on a
file-by-file basis. Or? If this is so, then scaling would be a _lot_
easier using <img>.

Do we need to / could we add an option to HTML export? Either export all
SVG files with <object> or <img>.
