[Paraview] screenshots in png format are big

[Burlen Loring]

it could be a bug if you saw a big increase in file size of saved png 
images between versions when rendering exactly the same scene. It'd be 
helpful if you could create a bug report, with steps to reproduce, and 
two png images that are different size.
