### Constants

### OpenLayers.Layer.Google.v3

Mixin providing functionality specific to the Google Maps API v3.

To use this layer, you must include the GMaps v3 API in your html.

Note that this layer configures the google.maps.map object with the “disableDefaultUI” option set to true. Using UI controls that the Google Maps API provides is not supported by the OpenLayers API.

### DEFAULTS

{Object} It is not recommended to change the properties set here. Note that Google.v3 layers only work when sphericalMercator is set to true.

>     {
>         sphericalMercator: true,
>         projection: "EPSG:900913"
>     }

### Properties

### animationEnabled

{Boolean} If set to true, the transition between zoom levels will be animated (if supported by the GMaps API for the device used). Set to false to match the zooming experience of other layer types. Default is true. Note that the GMaps API does not give us control over zoom animation, so if set to false, when zooming, this will make the layer temporarily invisible, wait until GMaps reports the map being idle, and make it visible again. The result will be a blank layer for a few moments while zooming.

### Functions

### loadMapObject

> loadMapObject: function()

Load the GMap and register appropriate event listeners.
