[Paraview] Paraview 3.4.0 accepting connections from multiple servers

[Utkarsh Ayachit]

Here's how you can specify the display to use for each server using a
configuration file called "pvx".

<pvx>
  <Process Type="server">
    <Machine Name="m1" Environment="DISPLAY=:0" />
    <Machine Name="m2" Environment="DISPLAY=:1" />
  </Process>
</pvx>

Now start the pvserver as:
> mpirun -np 2 <path>/pvserver <path>/configuration.pvx

Now connect to this server using the paraview client. If you set the
remote render threshold from the "Edit|Settings" dialog to 0 you will
see that the 2 server rendering windows will pop up on the two
displays.
