// This file contains the default implementation for the mac event loop. Events that
// pertain to the layout engine are routed there via a MessageSink that is passed in
// at creation time. Events not destined for layout are handled here (such as window
// moved).
//
// Clients may either use this implementation or write their own. Embedding applications
// will almost certainly write their own because they will want control of the event
// loop to do other processing. There is nothing in the architecture which forces the
// embedding app to use anything called a "message pump" so the event loop can actually
// live anywhere the app wants.
