[enhancement] Error in docs about drag&drop

[Alex-Github-Account]

The documentation mentoines "drag&drop " but component do not supports drag&drop (thy drag image onto component- nothing will happen) As far as I can understand, this is just a translations from russian language error. Where "drag&drop" is used in the docs, it actually should be 'pan' User can pan the image to crop it. also actual drag&drop will be cool since it is not hard to do in html5 nowadays

Ok looks like project abandoned, inevitable fate of small repos, this issue may be closed. I copied it and solved the bugs.
