FLayerThis method can be used to have a fast cloned layer.
The implementations should take care of not recreate this layer. Instead of this, is better to use the same source (driver) and deepclone the legend. Exception: the labels aren't deepcloned to avoid memory consumption.
Note: Labels are memory consuming to speed up layers like PostGIS and so on.

ObserverObservable object is changed and this
Observer has registered on it to receive notifications.
Implementations of this method will be called for each simple notification or, if a complex notification is created, for each of the child notifications.
In the latter case, don't assume any ordering in the notification between
this Observer and other Observers listening to the same
Observable.
In a complex notification scenario, if you want to receive only the
complex notification and not each of the child notifications, just
implement the ComplexObserver and prepare this method
implementation to handle receiving DefaultComplexNotification instances
as well as direct notification objects.
