The previous code checked all_w_positive in the if condition. Instead, always execute the bbox culling code and include all_w_positive at the end. We assume checking in the if is not beneficial because it's very unlikely that there is no primitive in a wave whose W are not all positive. This allows moving other things to the condition in the next commit.
