I started using MapBox in a project. When I am adding annotation with custom images, it is not centered correct. It is appears little bit lower of the original pins. 
Is it possible to change center point of the annotation image?

How it should be:

How it stands now:

```
- (MGLAnnotationImage *)mapView:(MGLMapView *)mapView imageForAnnotation:(id <MGLAnnotation>)annotation {
    MGLAnnotationImage *annotationImage = [mapView dequeueReusableAnnotationImageWithIdentifier:@"driverPinId"];

    if (!annotationImage) {
        UIImage *image = [UIImage imageNamed:@"DriverPin"];
        annotationImageWithImage:image reuseIdentifier:@"driverPinId"];
    }

    return annotationImage;
}

```
