[Paraview] Parallel rendering

[Emmanuel Colin]

Hi,

Having written a new reader for ParaView, and testing it in parallel
mode, we got the full rendering to be done in every created window (and
overlapping windows didn't cause any display problem, so there seems not
to be any compositing either).

With another reader, for example .vtu reader, only part of the rendering
is done in each window, and the different parts are composited in the
main window as expected.

Could someone point out at what we might have overlooked ?

Regards,
Emmanuel
