Node subclasses can now control whether their bounds (changes)
contribute to damage.
Tristate:
* Default: The node bounds contribute to damage if the node itself was
invalidated, observing hasSelfInval(). This is the default
behavior.
* ForceSelf: The node bounds contribute to damage, regardless of
hasSelfInval(). Used for domain-boundary nodes (e.g. Draw),
which gate blocked fragments (e.g. geometry, paint nodes).
* BlockSelf: The node bounds do not contribute to damage, regardless of
hasSelfInval(). Used for nodes which do not contribute
damage directly (e.g. paints, geometry).
