| class MCoeMessageObserver |
Interface for handling incoming window server messages.
This interface is used to enable FEPs to keep their settings synchronised across all running instances.
Anything that needs to be notified of messages that get sent by the window server's message-sending service should derive from this class and override its pure virtual function.
In addition, derived classes also need to call CCoeEnv::AddMessageObserverL() during construction and CCoeEnv::RemoveMessageObserver() in their destructors.

Handles window server messages.
Implementations should return EMessageHandled if they are able to handle the message, or EMessageNotHandled if the message is not appropriate to this observer.
Indicates whether the message was handled or not handled by the function.
