Extended ListContourPlot and ContourShading

Hi,

I have been using the ExtendGraphics`Contour` version
of ListContourPlot to generate contour plots from a
list of (x,y,z) irregularly space data points. ContourShading
does not appear to work with this extended option: try the example
in "Mathematica Graphics" pg 483,


Needs["ExtendGraphics`Contour`"]

d1 = Flatten[
      Table[Table[{r Sin[t], r Cos[t], r^2 Cos[t] Sin[t]}, {t, 0, 
            2Pi - 2Pi/(10r), 2Pi/(10r)}], {r, 10}], 1];

c = ListContourPlot[d1]


ContourShading -> True does not work. Nor does ColorFunction.
Please note that this is only a problem for data entered in
(x,y,z) format and NOT for data in array format (compare 
ListContourPlot[Table[x^2 + y^2, {x, -2, 2, .1}, {y, -2, 2, .1}]]).
Any ideas?

Many thanks,
