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 TBR= Change-Id: I843e683e64cb6253d8c26d8397c44d02a7d6026f Reviewed-on: https://skia-review.googlesource.com/91421 Reviewed-by: Florin Malita <fmalita@chromium.org> Commit-Queue: Florin Malita <fmalita@chromium.org>
