       XtRegisterDrawable - register a drawable with the Intrinsics event dispatcher


       void XtRegisterDrawable(Display* display, Drawable drawable, Widget widget);

       void XtUnregisterDrawable(Display* display, Drawable drawable);


       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.
