Side mirrors don't respect the widescreen adjustments

They seem to slide all over the place, and they are invisible when not looking to the sides. With a high enough FOV, this becomes noticeable.

I suspect that making the left mirror visible even when not looking to the sides may be difficult, but it would be nice to have.

Or maybe not, since the game already "supports" that - if you accelerate rapidly and the driver's head moves backwards enough, the mirror becomes visible:

I have since learned that this may be really difficult to fix - as D3D9 does not support negative viewport origin coordinates that would be "necessary" here to make the existing mirrors work without much trouble.
