Subject: Feature/cuda coverage (#1223)

* Add cubemap support.

* Add CUDA fence instrinsics.

* Added Gather for CUDA.

* Use the CUDA driver API as much as possible.

* * Support 1D texture on CPU
* WIP on 1D texture on CUDA
* Added simplified texture test

* Fix test.

* Improve texture-simple tests.
