I think this is really nice. With this changeset, the FLTK backend is
very nice to use for 2D plots (much better than both gnuplot and
matlab).

Well, then I'm gonna file a request :-) It would be great to have better
support for navigating in 3D. Basically, I think dragging the mouse
should make 3D plots rotate around some point (center of mass?), while
scrolling should change the distance between the camera and said point.
