/**
* nsIDragSessionOS2 encapsulates support for OS/2 dragover/drop events,
* i.e. operations where Mozilla is the target of a drag (nsIDragService
* handles source operations). Its public methods correspond to the d&d
* messages a PM window receives. Its protected methods recast native
* data as nsITransferable flavors during drag-enter and drop events.
*
* nsIDragSessionOS2 supports these native formats: WPS Url objects,
* files, the contents of files (Alt-drop), and text from DragText.
* Data is presented to Mozilla as URI-text, HTML, and/or plain-text.
* Only single-item native drops are supported. If the dropped file
* or text does not exist yet, nsIDragSessionOS2 will have the source
* render the data asynchronously.
