Wrong Scale during Zoom with new Google Maps API Renderer

[aemkei]

The Google Maps API has a new renderer that causes wrong position updates with the WebGL layer during the zoom.

See: https://developers.google.com/maps/documentation/javascript/new-renderer#troubleshooting

Would be great to have the overlay in sync!

I've made a patch referring to https://github.com/google-map-react/google-map-react/pull/559.
