[Feature Request] option to disable "border scroll"

Please add an option to disable scrolling the view whenever the mouse is near the border.

It would be useful to me as I play in windowed mode without the mouse being clamped to the window as I like to be able to quickly move in and out of the game window.

The border scrolling behavior is a bit distracting because it unintentionally happens while moving the mouse from inside to outside the window.
