XtRegisterDrawable - register a drawable with the Intrinsics event dispatcher

display   Specifies the drawable's display.

       drawable  Specifies the drawable to register.

       widget    Specifies the widget to register the drawable for.

XtRegisterDrawable  associates  the  specified drawable with the specified widget so that future calls to
       XtWindowToWidget with the drawable will return the widget.  The default event  dispatcher  will  dispatch
       future core events that arrive with the drawable to the widget as though the event contained the widget's
       window,  but  the event itself will not be changed in any way when being passed to even handler or action
       procedures.

       If the drawable is already registered with another widget, or if the drawable is the window of  a  widget
       in the client's widget tree, the results of calling XtRegisterDrawable are undefined.

       XtUnregisterDrawable  removes  an  association  created  with XtRegisterDrawable.  If the drawable is the
       window of a widget in the client's widget tree the results of calling XtUnregisterDrawable are undefined.
