struct SceneState

Defined at line 43 of file ../../src/ui/scenic/lib/flatland/engine/engine.h

Holds the cached global transform state generated from each Flatland session's `UberStruct`

and linked together by the `LinkSystem`. Recomputed only when a transform-level change is made

in the global scene graph (`needs_full_rebuild == true`). Public for testing.
