[Paraview] save 'Surface LIC' as texture

[Burlen Loring]

I think it could be done if you're willing to hack into PV. There is 
already some mechanism in there for sucking textures back from the gpu 
and writing them to disk for debugging. It's not exactly what you need 
but at least will illustrate pulling data from GPU.

a potential issue with this idea is that the result from the LIC is very 
view dependent, you may be restricted to use same view settings in your 
app/blender. maybe better just to write the LIC shader in blender.
