[Feature]: Inversed FOV distortion

[dobemon]

What is the new feature or improvement?

As raising the current FOV scale, the center of the screen shrinks as the edges stretch inward, making sprinting feel faster and swimming feel slower. When I want to have a wider view angle, there's a problem where things in front of me looks tiny and further away.
Is there any way you could refract(?) the stretched edges back and the center appear closer again, while keeping the fov somewhat as it is? It would be awesome if the intensity is scalable.

This looks like it'd probably be difficult, mostly because it involves calculating projection matrices and perspectives during rendering and I'm just not really familiar with it enough. I'll workshop this, but it's best to consider that this most probably will not be added.
