We add additional scope attribute position with params:

• size
• x
• y

For saving position for crop area

Hi. I needed your changes and since this project is not maintained anymore, I forked it and published it as osd-ng-img-crop on bower: https://github.com/Osedea/ngImgCrop

Not to put you on the spot or anything like it, but would this become the "official" fork?

That's not up to me to decide this, but feel free to use the fork. I just put it on bower because others could need it.
If one day @alexk111 works on it again, I could make a PR to merge back stuff.
