[vtkusers] parallel rendering from Python

[Kaushik .]

Hi

check out the vtkParallelRenderManager and vtkCompositeRenderManager
classes. They do sort last rendering if i remember properly.

Also there was some issue with running parallel examples in python. This has
to with not being able to pass
&argc and &argv from python to the MPI_Init function that has to be called
for parallel applications using MPI.

The settings you have written below do not enable the VTK_USE_MPI which may
be needed to run with MPI.


Note that the vtkCompositeManager has been done away with.

Will be able to mail you an example after a few days ( do not have access to
the pc where i have the examples currently ).
