The script examples/backend_driver.py does just this -- it runs a
most of the examples and generates output in a variety of formats
(PNG, PS, SVG). I usually tun this before releases and load all the
images into a viewer to check for bugs. We could add these generated
images to a web page...., but sourceforge is already complaining that
I am over my quota. Apparently, I can ask for more space, though.
