size_t features_shrink(const RoI_basic_t *RoIs_basic_src, const RoI_magn_t *RoIs_magn_src, const RoI_elli_t *RoIs_elli_src, const size_t n_RoIs_src, RoI_basic_t *RoIs_basic_dst, RoI_magn_t *RoIs_magn_dst, RoI_elli_t *RoIs_elli_dst)

Shrink features. Remove features when feature identifier value is 0. Source features (RoIs_X_src) are copied into destination features (RoIs_X_dst) if RoIs_basic[Y].id > 0.
