+//
+// There are three different ways to play an animation:
+//
+// 1. Start Animation.  This is the normal way to play an animation.
+// 
+// 2. Warp to Final.  Skip the actual animation, and jump
+//    instantaneously to the final state of the animation.
+// 
+// 3. Blend to Final.  Skip the actual animation, and blend
+//    smoothly to the final state of the animation.  If the current
+//    state is very far from the final state, then maybe jump instantaneously
+//    instead.
