Methods
_rebuildLists()
Rebuild lists for this drawable and notify any parent drawable to do so as well. This ensures each drawable contains an updated, flat list of all the drawables beneath them. This way we save performance by not recursing through each child during draw time, and instead, drawing from the flat list at the level we care about.
