	//Builds a Res32 file image of a resource from the resource's CLocItem objects

	//	- A pointer to a CLocItemPtrArray object containing the CLocItem objects of
	//	a resource (like a dialog or a menu).
	//	- An array index to the root item of the resource.
	//	- An array index to the selected item of the resource.

	//	- A pointer to an existing empty CFile.
	//  - A pointer to a Res32FontInfo structure
	//	- A pointer to a reporter object where all error messages are sent.
	//Outputs:
	//	- The CFile object has the res32 image of the resource.
	//	- The CLocItemPtrArray object has its items ordered by physical
	//	location in the res32 image.	
	//Return:

	//	- A pointer to a CLocItemPtrArray containing the CLocItem objects of the
