AppGameKit lacks the ability to "Lock Mouse to Screen" for when in Windowed Mode
I also couldn't see any examples (but then the Search is a bit 'meh' for these boards)
It's not perfect., but this will allow you "Lock" the Mouse to the Screen
Will continue to work and improve this... as switching between modes isn't seamless.
I also add functions for the Sprite Support (for Animated Sprites)
Other than that Mouse.Position.X/Y is the Window Position, Mouse.Movement.X/Y will tell you how much the Mouse moved since the last call
These two features should make using AppGameKit in Window Mode MUCH easier for Games, such-as Mouse Look.
