// -- this is a simple odd class provided for 'static' usage
|
|
// -- 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
