[OpenLayers-Dev] Re: Reduce OpenLayers.Layer.Grid's buffer throughout

[Matt Priour]

This will work but should be done AFTER you instantiate all your layers.
Otherwise, the defaults specified in the class will overwrite the prototype
value. When you do it after the instantiation then it will change all
instances of OpenLayers.Layer.Grid and all its subclasses.
