Prevent cursor from leaving window

When playing with multiple monitors, one can accidentally click outside the game window which minimizes it. The mouse cursor should be captured and prevented from leaving the game window.

This should be made configurable, as I personally prefer the current way

I have two monitors, and this never happens to me. I do have the "Extend these displays" in my Windows 10 Display settings though. I wonder if this is why it works ok for me. And in the Settings for this game, I have the 'borderless' option set.
