Zero-width strokes imply hairline in Skia, but in other models (e.g.
Lottie) they are simply ignored. The latter approach avoids
discontinuities when width -> 0, so let's make it the default for sksg.

Force an initial tick on animation initialization.
This prevents inconsistent state flashing if the client starts rendering

Backpedal on node/reval-time-determined damage: nodes cannot control
the invalidation order, and shared descendants may be revalidated before
a particular ancestor gets to query their state - thus making any
decisions based on that invalid.
Instead, apply damage suppression at invalidation time, based on node
type/traits. Node types which don't generate direct damage are marked
as such, and the invalidation logic bubbles damage past them, until it
finds a valid damage receiver.
Nodes which currently suppress damage:
- PaintNode (and subclasses)
- GeometryNode (and subclasses)
- Matrix

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).

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

Coarse workflow:
* Construction
1) build a Json tree
2) collect asset IDs (for preComp/image layer resolution)
3) "attach" pass
- traverse the Json tree
- build an SkSG dom, one fragment at a time
- attach "animator" objects to the dom, for each animated prop
4) done, we can throw away the Json tree
* For each animation tick
1) iterate over active animators and poke their respective dom nodes/attributes
2) revalidate the SkSG dom
3) draw the SkSG dom
Note: post construction, things are super-simple - we just poke SkSG DOM attributes
with interpolated values, and everything else is handled by SkSG (invalidation,
revalidation, render).
