Yes, I agree, but coupling this in scientific algorithms to heavily seems
a very very bad idea, IMHO. I think it should be made possible to get a
package with not one line related to graphics, or plotting, and of course
no printing on the screen.

Now adding the option of passing a few callbacks to do the plotting, but
not giving these callbacks in the core package is a different story.

Cheers,
