[Paraview] Bug in contour filter for version 3.12 not present in 3.10

[Russell M. Taylor II]

Paraview 3.12 doesn't let me check the "Compute Scalars" box, it is 
grayed out, in some circumstances.

Sources/Wavelet
FIlters/Clip
Filter/Contour

The above sequence will give you the situation I am talking 
about.  Version 3.10 of Paraview and earlier let you compute 
scalars.  If you can't, then you can't color by the scalar value 
(this is useful in the case of multiple contours).
