2d92988f6b Cycles: CUDA bicubic and tricubic texture interpolation support. 
While cubic interpolation is quite expensive on the CPU compared to linear
interpolation, the difference on the GPU is quite small.

23098cda99 Code refactor: make texture code more consistent between devices. 
* Use common TextureInfo struct for all devices, except CUDA fermi.
* Move image sampling code to kernels/*/kernel_*_image.h files.
* Use arrays for data textures on Fermi too, so device_vector<Struct> works.
