MetaSelectionSource represents a primary/clipboard/dnd selection owner, it is an abstract type so wayland/x11/etc implementations can be provided. These 3 selections are managed by the MetaSelection object, the current selection owners will be set there, and signals will be emitted so the previous selection owner can clean itself up. The actual data transfer is done through the meta_selection_transfer_async() call, which will take a GOutputStream and create a corresponding GInputStream from the MetaSelectionSource in order to splice them. https://gitlab.gnome.org/GNOME/mutter/merge_requests/320
