dWorldStepReserveInfo

@struct dWorldStepReserveInfo @brief Memory reservation policy descriptor structure for world stepping functions.

@c struct_size should be assigned the size of the structure.

@c reserve_factor is a quotient that is multiplied by required memory size to allocate extra reserve whenever reallocation is needed.

@c reserve_minimum is a minimum size that is checked against whenever reallocation is needed to allocate expected working memory minimum at once without extra reallocations as number of bodies/joints grows.
