		  I do not really understand the fashion in which widgets resize
themselves.  What I am trying to do is change the background pixmap in
a core widget, and have the form containing the core, and the shell
above that resize to the size of the pixmap.
 {
	Pixmap newpixmap, pixmap;
	int i;
	int x, y;
	unsigned int width, height, bw, depth;
	unsigned int width_return, height_return;
	Window rr;
	Arg args[15];
	XtGeometryResult result;

	XGetGeometry(XtDisplay(fullsizeform), newpixmap, &rr, &x, &y,
					 &width, &height, &bw, &depth);
	pixmap = XCreatePixmap(XtDisplay(fullsizeform), XtWindow(widget),
								  width, height, depth);
	XCopyArea(XtDisplay(fullsizeform), newpixmap, pixmap, myGC,
				 0, 0, width, height, 0, 0);
	newpixmap = full_size;
	full_size = pixmap;
	XtSetArg(args[0], XtNbackgroundPixmap, full_size);
	XtSetValues(graphic, args[0], 1);

   XFreePixmap(XtDisplay(fullsizeform), newpixmap);
}

This is pretty much the code I have used.  As you can see, I am not
sure whether to change the size with XtSetValues, XtMakeResizeRequest,
or XtResizeWidget.  Anyway, none of these changes the size of the widget.

The hierarchy looks like this:

		  A dialog shell->a form->a core.  I want the whole window to
change size to the new background pixmap.
