       Tk_CollapseMotionEvents(display, collapse)

       Tk_QueueWindowEvent(eventPtr, position)

ARGUMENTS
       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.

       Tcl_QueuePosition   position   (in)      Where to add the new event in  the  queue:   TCL_QUEUE_TAIL,

DESCRIPTION
       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.
