I'd hope that you can just handle the appropriate drag action:

I guess that theoretically the user could remap what action he means by
left and right drag and you should allow him to do that. Also, it's
probably easier than reimplementing the drag API.

Or maybe it's just modifier keys that determine which drag action is
meant. I'm not sure.
