OpenCL/Nvidia:

* Enable OpenCL Full Shading on NVIDIA cards.

Notes:
It makes not much sense to use OpenCL on a nVidia card (as it is slower compared to CUDA), but as OpenCL comes without dependencies, it's an good alternative if you don't want to install the CUDA toolkit or the build comes without CUDA kernels.
