[Paraview] Paraview v3.4.0 poor movie quality

[David E DeMarle]

It looks like paraview 2.6's animation quality setting (low, medium,
high) was lost in the transition to 3.x. The result is that 3.x
chooses medium as the default.

I've added bug 8427 to the bugtracker so that it will get resolved by
3.6. In the meantime, if you build from source, you can change

vtkSMAnimationSceneImageWriter.cxx line 60 to be
this->Quality = 2; //for max
or
this->Quality = 0; //for min
