Detailed Description

Shared rendering model consumed by both the GAL renderer (interactive widget) and the plotter renderer (headless PNG/SVG output).

The scene is a flat list of "shapes to draw" derived from a DOCUMENT_DIFF. Currently each shape is just a colored rectangle around the changed item's bbox; a future revision can pull the actual item geometry from the source board/schematic for a true overlay render.

Color palette is set by the consumer (UI colors come from the user's theme; CLI uses a fixed printable-on-light-bg default).

◆ changeId

KIID_PATH KICAD_DIFF::SCENE_SHAPE::changeId

Stable identifier of the ITEM_CHANGE that produced this shape.

Used by the interactive widgets to cross-probe between change tree selection and the rendered scene without relying on bbox equality (two distinct changes can share an enclosing rectangle).
