Tk_CollapseMotionEvents, Tk_QueueWindowEvent - Add a window event to the Tcl event queue

       Display *display (in)                    Display for which to control motion event collapsing.

       int collapse (in)                        Indicates whether motion events should be collapsed or not.

       XEvent *eventPtr (in)                    An  event  to  add  to the event queue. It is important that all
                                                unused fields of the structure be set to zero.

       Tcl_QueuePosition position (in)          Where to add  the  new  event  in  the  queue:   TCL_QUEUE_TAIL,
                                                TCL_QUEUE_HEAD, or TCL_QUEUE_MARK.

Tk_QueueWindowEvent  places  a  window  event  on  Tcl's internal 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 window in rapid succession, they are  collapsed  by
       default.   This  behavior can be controlled with Tk_CollapseMotionEvents.  Tk_CollapseMotionEvents always
       returns the previous 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.
