Florin Malita 0ebf4192f1 [sksg] More inval fiddling
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).
