title: fitBounds in GoogleMaps SDK for ios does not fit
body: <p>I want use fitBounds method in GoogleMaps for ios SDK and view does not fit. My varaibles are all right (path, arrays, etc...) because I can see polyline with markers on map. The only thing that does not work is fit to view. Where I have made mistake? thank you.</p>
  
  <pre><code>// Create a 'normal' polyline.
  GMSPolyline *polyline = [[GMSPolyline alloc] init];
  GMSMutablePath *path = [GMSMutablePath path];
  
  locationInfoArray = [LocationInfoMemoryManager loadLocationDataWithPath:_locationInfoPathString];
  
  for (int i=0; i&lt;locationInfoArray.count; i++) {
      LocationInfo* locationInfo = locationInfoArray[i];
      CLLocationCoordinate2D locationPoint = {locationInfo.latitude, locationInfo.longitude};
      [path addCoordinate:locationPoint];
  }
  
  
  GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:[locationInfoArray[0] latitude]
                                                          longitude:[locationInfoArray[0] longitude]
                                                               zoom:5 ];
  
  
  mapView = [GMSMapView mapWithFrame:CGRectZero camera:camera];
  
  polyline.path = path;
  polyline.strokeColor = [UIColor blueColor];
  polyline.strokeWidth = 10.f;
  polyline.zIndex = 15;  // above the larger geodesic line
  polyline.map = mapView;
  
  GMSMarker *startMarker = [[GMSMarker alloc] init];
  startMarker.title = @"Start";
  startMarker.snippet = @"Info will be here";
  startMarker.position = CLLocationCoordinate2DMake([[locationInfoArray firstObject] latitude], [[locationInfoArray firstObject] longitude]);
  startMarker.map = mapView;
  startMarker.flat = NO;
  //sydneyMarker.rotation = 30.0;
  mapView.selectedMarker = startMarker;
  
  GMSMarker *finishMarker = [[GMSMarker alloc] init];
  finishMarker.title = @"Finish";
  finishMarker.snippet = @"Info will be here";
  finishMarker.position = CLLocationCoordinate2DMake([[locationInfoArray lastObject] latitude], [[locationInfoArray lastObject] longitude]);
  finishMarker.map = mapView;
  finishMarker.flat = NO;
  mapView.selectedMarker = finishMarker;
  
  //Here is probably problem
  
  GMSCoordinateBounds *bounds; = [[GMSCoordinateBounds alloc] initWithPath:path];
  GMSCameraUpdate *update = [GMSCameraUpdate fitBounds:bounds withPadding:20];
  [mapView moveCamera:update];
  
  self.view = mapView;
