[Paraview] incorrect python tutorial: http://www.paraview.org/Wiki/ParaView/Python/Screenshot ?

	I've updated the tutorial. You're missing a "CreateRenderView" call
	for pvpython. I am guessing the contributor was using the UI for the
	script.

Thank you.

It seems the same page is available at two URLs:

http://www.paraview.org/Wiki/ParaView/Python/Screenshot

Thanks

Anton
