[vtkusers] vtkImageMapToColors vtkWindowLevelLookupTable

[David Gobbi]

This might be related to the following known bug:
https://gitlab.kitware.com/vtk/vtk/issues/16966

The bug occurs if you build the table by calling
lookupTable->SetTable(array).  If this is the case, you can work around
this by instead building the table by calling lookupTable->SetTableValue(i,
r, g, b, a) for every color.
