Hello Bill,
I used visad source updated from cvs.VisAD.sourceforge.net today, and
modified ShadowType.java and ContourControl.java.
bvalues[0] always seems to be true, spatialManifoldDimension is always
2, and fvalues[0] is always NaN.
Here is a series of stack traces, using DisplayImpl.printStack(), from
when the behaviour is seen.
Thanks
Russell
