Event controller for motion events during a drop. 
Gtk::DropControllerMotion is an event controller meant for tracking the pointer hovering over a widget during a drag and drop operation.
It is modeled after Gtk::EventControllerMotion so if you have used that, this should feel really familiar.
The drop controller is not able to accept drops, use Gtk::DropTarget for that purpose.
- Since gtkmm 3.98
