getTile

Returns a Tile based on X, Y and Zoom This method is called by the Map in a synchronous manner, so all methods called from this will have to be fast and reliable to not slow anything down.

We always try to get a local tile first, and if it doesn't exist, we'll get it and save it for later use

Also be aware, that searching for usages on this method will not return any useful information regarding WHERE we're using it, as is called by Google only.
