@brief Set the depth of the surface layer around all geometry objects.
@ingroup world
@remarks
Contacts are allowed to sink into the surface layer up to the given
depth before coming to rest.
@param depth The default value is zero.
@remarks
Increasing this to some small value (e.g. 0.001) can help prevent
jittering problems due to contacts being repeatedly made and broken.
