[Paraview] Update Slice Filter / Python Equivalent of "Apply"

[Berk Geveci]

Hi David,

The python code to achieve what you want should look like:

pm        = servermanager.ProxyManager()
mha_slice = pm.GetProxy("sources","mha_slice")
mha_slice.CutFunction[0].Normal = [1, 0, 0]

assuming that mha_slice is a Cut (slice) filter. I found a bug that
causes this to not work. I will fix it. For now, try this:

pm        = servermanager.ProxyManager()
mha_slice = pm.GetProxy("sources","mha_slice")
mha_slice.CutFunction[0].SMProxy.GetProperty("Normal").SetElement(0, 1)
mha_slice.CutFunction[0].SMProxy.GetProperty("Normal").SetElement(0, 0)
mha_slice.CutFunction[0].SMProxy.GetProperty("Normal").SetElement(0, 0)
servermanager.GetRenderView().StillRender()

PS: StillRender() is roughly equivalent to Apply
