Module eval 

Numeric evaluation of entities: world anchors, drawable shapes and texts.

Built-in entities use their canonical geometry; dimensions are computed from the anchors they reference; plugin entities are evaluated from their compiled definition; entities whose plugin is missing, disabled or too old fall back to their stored standard representation and are read-only.
