This class implements an animated mesh. The mesh animation is defined by keyframes and each keyframe if made of an array of vertex positions. The mesh can be represented by a group of strip/fans or just the separate triangles. The complete mesh must have a single texture and to interpolate the animation, use the set_key function.
