// IMPORTANT NOTE on System.ScreenWidth and System.ScreenHeight:
|
|
// It appears that in AGS these properties were not defining actual window size
|
|
// in pixels, but rather game frame size, which could include black borders,
|
|
// in 'native' (unscaled) pixels. This was due the specifics of how graphics
|
|
// modes were implemented in previous versions.
|
|
//
|
|
// Quote from the old manual:
|
|
// "Returns the actual screen width that the game is running at. If a graphic
|
|
// filter is in use, the resolution returned will be that before any
|
|
// stretching by the filter has been applied. If widescreen side borders are
|
|
// enabled, the screen width reported will include the size of these borders."
|
|
//
|
|
// The key words are "the resolution returned will be that BEFORE any
|
|
// stretching by the filter has been applied".
|
|
//
|
|
// Since now the letterbox and pillarbox borders are handled by graphics
|
|
// renderer and are not part of the game anymore, these properties should
|
|
// return strictly native game size. This is required for backwards
|
|
// compatibility.
