Subject: Texture Sample available in CUDA (#1176)

* WIP: Trying to figure out how texturing will work with CUDA.

* WIP: Fixes for CUDA layout. Initial CUDA texture test.

* WIP: Outputs something compilable by CUDA for TextureND.Sample

* 2d texture working with CUDA.

* Fix how binding for SamplerState occurs in CUDA.

* Small tidy up of comments.
