+// -- to calculate max. usage of a preferred  menue size (x,y)
+// -- this is due to 16:9 TV zoom functions, which are cutting menues.
+// -- so using this function will make menues to obey max. screen settings.
+// 
+// usage:  e.g.  try to paint menue h: 500 w, 400  (but screen is limited
+//         to (450 x 420)), functions will return 450 and 400
+//         the _add factor is for boundary...
+//
+//         16:9 Zoom-Mode on a Thomson TV set will e.g. be 625x415
