* This method attempts to make aResponder the first responder.<br />
* If aResponder is already the first responder, this method has no
* effect and simply returns YES.
* Otherwise, the method sends a -resignFirstResponder message to the
* current first responder (if there is one) and immediately returns NO if
* the current first responder refuses to resign.<br />
* Then the method asks aResponder to become first responder by sending
* it a -becomeFirstResponder message, and if that returns YES then this
* method immediately returns YES.<br />
* However, if that returns NO, the receiver is made the first responder by
* sending it a -becomeFirstResponder message, and this method returns NO.<br />
* If aResponder is neither nil nor an instance of NSResponder (or of a
* subclass of NSResponder) then behavior is undefined (though the current
* GNUstep implementation just returns NO).
