Merged requested to merge kmorel/vtk-m:clip-implicit-interp-any-field into master
MR !2969 (merged) was meant to update the clip filters such that their field
mapping works on any field type and preserves the value type. Although
this was done for
ClipWithField, it was not fully implemented for
ClipWithImplicitFunction. These changes update
ClipWithImplicitFunction to match its sibling.
