Rendering/OSPRay to be renamed Rendering/RayTracing in VTK 9.0

Hey folks,

Just a heads up that starting with VTK master as of Yesterday, the OptiX rendering module has been removed and the OSPRay module has been renamed RayTracing, which is now capable of using both back ends. The OptiX specific implementation inside is now a path tracer, with full materials support.

cheers

Awesome stuff. Thanks to Dave and Tim.
I integrated that into my first demo.
The OptiX denoiser is amazing.
