[vtkusers] Speed Up Rendering Colored Point Cloud

[Ken Martin]

If you want to go to the extreme and you are willing to hack around a
little  bit you can use vtkLODPointCloudMapper. It is a bit behind VTK so
the build may need to be modified. But it can render a 100 million point
dataset at a rate of 1 billion points/second without much grief on my
laptop (gtx 960M) You can find some talk about it here...
