OK, I made a filled contour function (vtk_contourf).  It should be 
available in cvs shortly 
(http://cvs.sourceforge.net/viewcvs.py/octaviz/octaviz/Scripts/), and I 
added a screenshot to the webpage 
(http://octaviz.sourceforge.net/index.php?page=screen).

It probably isn't the best implementation.  Basically it renders a 
surface plot and flattens it, then it adds black contour lines over the 
top.  Since I don't use contour plots very much (I prefer 3d surface 
plots), you can tell me if it meets your needs or not.  Another helpful 
function available in CVS that is not in the last release is vtk_colormap.
