◆ WM_drag_free_imported_drag_ID()

void WM_drag_free_imported_drag_ID	(	struct Main *	bmain,

	)

Free asset ID imported for cancelled drop.

If the asset was imported (linked/appended) using WM_drag_get_local_ID_or_import_from_asset()` (typically via a wmDropBox.copy() callback), we want the ID to be removed again if the drop operator cancels. This is for use as wmDropBox.cancel() callback.

When dragging a local ID, return that. Otherwise, if dragging an asset-handle, link or append that depending on what was chosen by the drag-box (currently append only in fact).

Use WM_drag_free_imported_drag_ID() as cancel callback of the drop-box, so that the asset import is rolled back if the drop operator fails.
