[vtkusers] Reverse color in vtkScalarsToColors?

[Cory Quammen]

vtkScalarsToColors is the base class for color maps. Try
SafeDownCasting the pointer returned by the mapper to vtkLookupTable.
If the returned color map is not an instance of vtkLookupTable, try
setting your own lookup table with something like

vtkSmartPointer<vtkLookupTable> myTable =
vtkSmartPointer<vtkLookupTable>::New();
myTable->SetHueRange(...);
// other lookup table setup here.
shape_actor->GetMapper->SetLookupTable(myTable);

HTH,
Cory
