* Rename "texture" to "data array". This has not used textures for a long time, there are just global memory arrays now. (On old CUDA GPUs there was a cache for textures but not global memory, so we used to put all data in textures.) * For CUDA and HIP, put globals in KernelParams struct like other devices. * Drop __ prefix for data array names, no possibility for naming conflict now that these are in a struct.
