// Restores the Scaleform scale modes menus were loaded with before Skyrim 1.6.1130.
// Restores the Scaleform scale modes menus were loaded with before Skyrim 1.6.1130, and stops
// kNoBorder from cropping them on displays wider than 16:9.
//
// 1.6.1130 switched nearly every menu to kExactFit, which stretches the movie across the whole
// viewport instead of preserving its aspect ratio. Enderal's menus - including the SkyUI-derived
// widescreen versions shipped with them - are authored for the old modes, so on anything that is
// not 16:9 they come out distorted.
//
// The table below is what 1.6.640 passes to BSScaleformManager::LoadMovie. Menus the update left
// alone (Book, BookMenu, Console, CreditsMenu, CursorMenu, FaderMenu, GiftMenu, StartMenu) are
// deliberately absent and keep whatever the caller asked for.
// The table below is what 1.6.640 passes to BSScaleformManager::LoadMovie, plus BookMenu and
// GiftMenu, which 1.6.1130 left on kNoBorder and which need the same clamp. Menus that want no
// help (Book, Console, CreditsMenu, CursorMenu, FaderMenu, StartMenu) are absent and keep
// whatever the caller asked for.

// The movie gets the whole framebuffer as its viewport, so kNoBorder scales a 1280x720 menu
