	//	Parameters: 
	//		theApp	- Pointer to the main application class 
	//	 
	//	Returns: none 
	//////////////////////////////////////////////////////////////////////////

	////////////////////////////////////////////////////////////////////////// 
	//	Function: Init 
	//	Parameters: none 
	//	Returns: none 
	// 
	//	Purpose: Called BEFORE the title screen is added to the widget manager 
	//	by GameApp. This initializes some things like the images used for 
	//	our hyperlink widget. 
	//////////////////////////////////////////////////////////////////////////	 
	void Init(void);

	//	Function: AddedToManager 
	//	Parameters: 
	//		theWidgetManager	- Pointer to the main widget manager from 
	//								GameApp. 
	// 
	//	Returns: none 
	// 
	//	Purpose: This function is automatically called by the widget manager 
	//	which also passes a pointer to itself, when the TitleScreen class is 
	//	added to its list of widgets. Every widget gets this function 
	//	called when it is first added. It useful to use this function to 
	//	set up any other widgets that the class might contain, such as buttons. 
	//////////////////////////////////////////////////////////////////////////

	//	Parameters: 
	//		theWidgetManager	- Pointer to the main widget manager from 
	//								GameApp. 
	// 
	//	Returns: none 
	// 
	//	Purpose: This function is automatically called by the widget manager 
	//	which also passes a pointer to itself, when the TitleScreen class is 
	//	removed from its list of widgets. Every widget gets this function 
	//	called when it is finally removed. It useful to use this function to 
	//	also remove any widgets that were added and created in AddedToManager. 
	//////////////////////////////////////////////////////////////////////////

	//	Function: ButtonDepress 
	//	Parameters: 
	//		theId	- Integer ID of the button that was clicked 
	// 
	//	Returns: none 
	// 
	//	Purpose: This method is called by the WidgetManager when a button widget 
	//	is first pressed and THEN released. You can use ButtonPress if you want 
	//	to know when the button is first pressed (before it is released). 
	//	theId is the integer ID that was assigned to the button when it was 
	//	first created.

	//	Function: Draw 
	//	Parameters: 
	//		g	- Graphics object used to draw all images and fonts to the screen. 
	//	 
	//	Returns: none 
	// 
	//	Purpose: Called automatically by GameApp's WidgetManager. This is where 
	//	we'll do all our display routines for the loading screen. 
	////////////////////////////////////////////////////////////////////////// 
	void Draw(Graphics* g); 
 
	////////////////////////////////////////////////////////////////////////// 
	//	Function: LoadingComplete 
	//	Parameters: none 
	//	Returns: none 
	// 
	//	Purpose: Called manually by GameApp when we are done loading all 
	//	resources, to let the title screen know that it should unhide and 
	//	enable the continue link, so the user can start playing the game.
