// This header contains the mission classes for the GUI

// GUI is now single update driven.  An event comes in, the manager decides who its for
// and passes the event down.  Eveything still know how to draw etc.
//
// All drawing is done through gos_drawQuad and drawTriangle
//
// Basic cycle is 
//		call GObject->update with this frame's events.
//			This will check the events to see if any pertain to me.
//			Draw anything to the texture plane that needs drawing.
//			Call any code which the events might have trigged.
//		call GObject->render with this frame's events.
//			This draws the object to the screen.
//			called in order of depth.

	// It has an update which is called every frame.
	//
	// It has an init which takes a FIT file and creates the interface
	// from the .FIT file.  This allows artists to correctly setup
	// the interface for each screen using data files.
	//
	// Its also has a render which is called AFTER the camera render
	// so that the interface ALWAYS sits on top of the world.

	// It has an event constructor to create events and pass them down
	// the interface chain.
