[vtkusers] Visualisation from OpenCL

[David E DeMarle]

Specifically look at the RenderOnGPU path in vtkPistonMapper in the
current development branch.

It uses cuda_gl_interop to hand the mesh that sits in thrust space
directly to openGL for rendering. A quick google search tells me that
you should be able to do the same thing from openCL.
