The purpose of this call is to initiate a drag operation.
A drag can span several calls to Wimp_Poll, so applications must remember what is being dragged and why.
The termination of a non system drag is reported by the User_Drag_Box event code.
Aborted non system drags (for example when an error box is shown) are not reported.
