DESCRIPTION
       Tk_QueueWindowEvent places a window event on Tcl's  inter-
       nal  event  queue  for  eventual  servicing.  It creates a
       Tcl_Event structure, copies the event into that structure,
       and  calls  Tcl_QueueEvent  to add the event to the queue.
       When the event is eventually removed from the queue it  is
       processed just like all window events.

       When multiple motion events are received for the same win-
       dow in rapid succession, they are  collapsed  by  default.
       This  behavior  can  be controlled with Tk_CollapseMotion-
       Events.  Tk_CollapseMotionEvents always returns the previ-
       ous value for collapse behavior on the display.

       The  position argument to Tk_QueueWindowEvent has the same
       significance as for Tcl_QueueEvent;  see the documentation
       for Tcl_QueueEvent for details.
