Add some kind of natural rendering

[CommonLoon102]

Linear projection distorts the image at the edges of the screen.
To fix this, add an option which would work similarly to Fovotec's Fovorender technology.
This would enable players to play on 21:9 displays at 140 FOV or even larger without distortion at the edges.
