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

/// @defgroup unsafe Chipmunk Unsafe Shape Operations
/// These functions are used for mutating collision shapes.
/// Chipmunk does not have any way to get velocity information on changing shapes,
/// so the results will be unrealistic. You must explicity include the chipmunk_unsafe.h header to use them.
