Detailed Description

Axis-aligned bounding box used for repaint-rect math.

Local-coordinate bounds are reported by local_bounds(); the scene walker composes a node's transform onto its parent to derive "scene" bounds when the host asks for the bounding box that needs to be repainted after a mutation.
