A TurtleWoW 1.12.1 addon that shows the healing returned by the Vampirism item stat.
The game emits no event for that healing, so the addon computes it from the player's own
outgoing damage using a formula measured in-game, and shows it live on a movable bar with a
per-ability breakdown, an overheal split, automatic source detection from equipped gear, and
optional scrolling combat text.
