alternatives?
- use a single big 1D texture, and do our own lookup/filtering
- group by size and use a 3d texture, performance impact
- group into larger texture with some padding for correct lerp
also note that cuda has 128 textures limit, we use 100 now, since
we still need some for other storage */
