Graphics: Add 1.5 scaler
|Reported by:||bluegr||Owned by:||sev-|
It would be nice to add a 1.5 scaler to the ScummVM, especially for 640x480 games. The reason is that 640x480 is too small for a window and the 2x scaler makes it too big (1280x960).
The 1.5 scaler converts the resolution to somewhat better numbers (960x720), which is not a proper fullscreen resolution, but it would be great for windowed mode
So, this scaler could be available only in windowed mode via Control-Alt-"+" and Control-Alt-"-" or another shortcut (e.g. Control-Alt-"s")
