//  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.   //
