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

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.
