Basically, the actions just give the application information
about what it is supposed to do. GTK+ doesn't actually try
to implement the action itself.

The one partial exception to this is that if you specify
GTK_DEFAULT_DROP on the destination, then on succesful
completion of a drop, GTK+ will tell the source to
delete the data. If the source is a GTK+ application,
what happens then is that the source widget receives
a "drag_data_delete" signal.
