Supports both smoke/fire and point density textures now. Reduces number of textures available for sm_20 and sm_21, but you have to compromise somewhere on such a limited hardware. Currently limited to linear interpolation only, and decoupled ray marching is not supported yet. Think those could be considered just a further improvement. Some quick example: https://developer.blender.org/F282934 Code is minimal and we can fully consider it a fix for missing support of 3D textures with CUDA.
