title: Getting the bounds of a polyline in Google Maps API v3
body: <p>Is there any easy ways to find the bounding box of a polyline using Google Maps API v3? I'm working on a project where I need to update the bounds as data is added and removed from the map. This is pretty easy by just doing bd.extend(point) where bd is the bound object and point is a LatLng object. The problem is when I start removing data I would like it to change the bounds and zoom back in. Are there any built in functions that can do this or will I need to write something for myself?</p>
