22 /* This header defines a number of "unsafe" operations on Chipmunk objects.
23  * In this case "unsafe" is referring to operations which may reduce the
24  * physical accuracy or numerical stability of the simulation, but will not
25  * cause crashes.
26  *
27  * The prime example is mutating collision shapes. Chipmunk does not support
28  * this directly. Mutating shapes using this API will caused objects in contact
29  * to be pushed apart using Chipmunk's overlap solver, but not using real
30  * persistent velocities. Probably not what you meant, but perhaps close enough.
