[vtkusers] Opacity in Points representation

Opacity in surface rendering is generally only controllable at the
actor level within the GUI.

However, if your data happens to have a 4 component unsigned char
RGBA, and you tell ParaView to use that array as the color directly,
you can do it.

The attached state file demonstrates.
