[Paraview] Problems with displaying labels floating over data points

[Utkarsh Ayachit]

Creating a DataLabelRepresentation should have worked. Here's a Python
script that illustrates the same:

from paraview.simple import *
s = Sphere()
r = Show()
v = Render()
l = servermanager.rendering.DataLabelRepresentation()
l.Input = s
l.PointLabelVisibility = 1
l.PointLabelMode = "IDs"
v.Representations.append(l)
Render()
