Current behavior
Lets say you have a large data set, that is is bigger than one screen. If you drag an item, and move it to the bottom of the page, the page does not auto scroll down, like nearly every other drag library. However, if you start dragging something, you can use a mouse wheel to scroll the page down to drop the item where you desire. I am not sure if this is what has been mentioned in #26 but it doesn't seem clear that this is the exact problem/cause of the issue.

Expected behavior
Moving a draggable item to the edge of a screen space, should auto move the screen in the direction in which you are dragging to show and expand the area you want to drag to.

What is the motivation / use case for changing the behavior?
Improved functionality with large UI's where items need to be dragged to a area of the screen that may not be visible in the current view.

This is not something currently supported by dragula, when we replace (it is planned) we look into this.
