Extracts the transform on the indicated Soft node, as appropriate for a joint in an animated character, and applies it to the indicated node.
This is different from get_transform() in that it does not respect the _transform_type flag, and it does not consider the relative transforms within the egg file. more added functionality: now fills in components of anim (EffXfmSAnim) class (masad).
