-/* == POSE 'SLIDING' TOOLS == 
- *
- * A) Push & Relax, Breakdowner
- * These tools provide the animator with various capabilities
- * for interactively controlling the spacing of poses, but also
- * for 'pushing' and/or 'relaxing' extremes as they see fit.
- *
- * B) Propagate
- * This tool copies elements of the selected pose to successive
- * keyframes, allowing the animator to go back and modify the poses
- * for some "static" pose controls, without having to repeatedly
- * doing a "next paste" dance.
- *
- * C) Pose Sculpting
- * This is yet to be implemented, but the idea here is to use
- * sculpting techniques to make it easier to pose rigs by allowing
- * rigs to be manipulated using a familiar paint-based interface.
