	Number of solver contacts; see r2SolverContacts.
uint32_t	user_data
	Application data, persistent across steps and editable by contact-modification hooks.

Detailed Description

Geometric contact manifold of a contact pair: contacts sharing one normal.

Local data follow the pair's own collider1/collider2 order (see r2ContactPair).
