LeafState

The derived leaf-probe state of one item (§LPD-7): its chain and its leaf world.

In the namespace construct::model. Declared in src/libs/libconstruct/construct/model/SceneItem.hpp.

Detailed description

A SceneItem holds it behind one shared pointer, never by value. By value it put about 250 bytes on every SceneItem and every Instance, and test frames that hold a few Instances crossed -Wstack-usage. Most items have neither half, so most items share nothing at all.
