Description

Low-level bindings to the enums and configuration structs of box2d/types.h needed to create and configure worlds, bodies and shapes.

The *Def structs carry an internalValue magic that Box2D uses to detect an initialised definition, so always start from the matching default* constructor and tweak the fields you need before use. Every C bool maps to CBool (one byte), and opaque callback / userData pointers are kept as Ptr () until the callback layer lands.
