%D This is a rather old style, adn I used it for a presentation about \MATHML\
%D around the turn of the century. Unfortunately I can't find back that weird
%D presentation. I didn't change the code apart from loading the body font. One can
%D clock on an area and get it large. Clicking elsewhere brings back the main page.
%D It was actualy a zoom test at that time.
