(Migrated from wishlist)

Requested by cin.

Add support of pose animation (vertex and normal with any weight). Example: We have original model and and two "shots" with different positions of some vertex. In model we have "animation track" which contains weights on different time. When engine play the track, it get interpolated weight and compute new vertexes positions relative by original. Also interpolated normals. (May be this need do more better than I wrote :)
