The Crop feature often seems to crop out a little too much of the screen in the games I play, so I wanted to request the ability to enter a custom crop size. The user could probably just enter a set width and height for the crop and maybe even where the crop is centered e.g. middle, top-left etc.

This could also help to crop out any garbage sprites that can often surround the edges of the game screen in certain titles.
