Don't move pixel values to other side of screen

I was getting some distortion on the edge of a black screen section (looks like bleed from the other side of the screen, see first image below), this fixes that issue. I might be missing something else you were trying to do though!

It should be more of a option to turn this off, it is good for most pictures.
