public class DropControllerMotion extends EventController
`GtkDropControllerMotion` is an event controller tracking
the pointer during Drag-and-Drop operations.

It is modeled after [class@Gtk.EventControllerMotion] so if you
have used that, this should feel really familiar.

This controller is not able to accept drops, use [class@Gtk.DropTarget]
for that purpose.
