We need to discriminate between nodes whose bounds updates contribute to the dirty
region, and nodes whose bounds changes do not.
E.g. animated shape in a group: the animated shape node bounds should yield damage,
but the ancestor group bounds should not.
To accomplish this, we refine the invalidation state:
1) self invalidation == the node itself was invalidated, and its bounds updates
yield damage.
2) descendant invalidation == the node has some (self-)invalidated descendant,
but its own bounds are not contributing damage.
Also:
* hoist the bounding box invalidation logic into the base class (Node::revalidate)
and update to respect the states described above.
* remove (now-redundant) GeometryNode bbox logic.
* update revalidation methods to return the node bbox instead of void
