//																			//
//	9.21.2001 mcn - Added pfLogDisplays. These are classes that represent 	//
//					a scrolling buffer, much like the console, for on-		//
//					screen display of error logs and the such. Currently	//
//					managed by the console, but hopefully once we have		//
//					a general manager for dialogs/menus (debug or			//
//					otherwise), that manager will take the displays over.	//
