[Paraview] transparency of a surface

[Shigenobu Hirose]

Hi Robert,

While 3.3.0 is being built, I tried the same thing with old paraview-2.6.2.
Then I got an identical result to yours; the opacity control in the
display panel worked.

So, I suspect something wrong with 3.2.1 at least for the transparency.
