Is it possible to Mantain the Scalar Data After Decimation?

Hello,

After the decimation process are all the scalar information of cells and points lost?

Thank you,

```
vtkSmartPointer<vtkDecimatePro> decimator = vtkSmartPointer<vtkDecimatePro>::New();
decimator->SetInputData(inputPolyData);
decimator->SetFeatureAngle(featureAngle);
decimator->PreserveTopologyOn(); // Preserve topology, including scalars
decimator->Update();

vtkSmartPointer<vtkPolyData> decimated = vtkSmartPointer<vtkPolyData>::New();
decimated->ShallowCopy(decimator->GetOutput());

// Now, transfer the scalars from the original dataset to the decimated dataset
decimated->GetPointData()->AddArray(inputPolyData->GetPointData()->GetScalars());
decimated->GetCellData()->AddArray(inputPolyData->GetCellData()->GetScalars());
```
