Although the visibility enabler worked to turn on and off AnimationPlayer as it enters and exits the view frustum, this was of little use as bones animation and especially software skinning still take place driven by the AnimationTree node. This PR adds the ability to turn on and off AnimationTree, and AnimationTreePlayer nodes as they enter or exit the view frustum, which achieves the intention of switching off expensive animation processing.
