[PD] drag and drop - tkdnd on osx

[Dan Wilcox]

It seems like the plugin could use a companion "drop target" object, like a cnv but registers drops and sends a message like "$arg $arg $arg was dropped on me."

My structure is like this now (parent) -> (GOP-playlist) -> (GOP-track) so i drop the files into the track. Which works great if i place the GOP at margin 0/0. Now i can have several playlists in my parent and all is fine until the window gets scrolled, then the positions are off and drop is recognized at a wrong place.
