[vtkusers] enumeration labels

[N Smethurst]

You're probably better off using a 2D actor that is positioned using world 
coordinates. The quality of the font is also better than the follower's.

Here's a bit of code in my app:

    axisLabelProperty = vtkTextProperty::New();
    axisLabelProperty->SetFontSize(12);
    axisLabelProperty->SetJustificationToCentered();
    axisLabelProperty->SetVerticalJustificationToCentered();
    axisLabelProperty->SetLineSpacing(0.8);
    axisLabelProperty->SetColor(0.0, 0.0, 0.0);

    axisLabelMapper = vtkTextMapper::New();
    axisLabelMapper->SetTextProperty(axisLabelProperty);
    axisLabelActor = vtkActor2D::New();
    axisLabelActor->SetMapper(axisLabelMapper);
    axisLabelActor->GetPositionCoordinate()->SetCoordinateSystemToWorld();
    axisLabelActor->GetPositionCoordinate()->SetValue(x, y, z);
    axisLabelMapper->SetInput("my label");
