[vtkusers] performance problems with VTK java wrappers

[Jeff Lee]

Hi Rajesh,
Paraview is probably not using displaylists.  You could try
mapper.SetGlobalImmediateModeRendering(1);
which will turn off the use of displaylists.  There is otherwise no 
fundamental reason they should differ in performance.
