It would be a convenience to add a delegate call just before the addDraggableIndicatorsToCell: animation block. Something like
dragTableViewController:willDragCell:forIndexPath:
in order to prepare the cell for the drag animation.
Use case: my table cells are borderless images, and the stock shadow tends not to be visible when the images are dark. So I've replaced the shadow effect with a slight enlargement of the cell, which works well. I need to composite an overlay imageview to do this right. I'd prefer to do the compositing in a willDrag call. (My workaround is to always composite the overlay for all cells, and control it with .hidden, which is of course not animatable, so I can get the effect I want by setting it to NO inside the animation block.)
