	The way I prefer to do it is to define a UserProc which handles
drawing the dialog.  That way I'm sure that anytime it needs to be drawn
it will be.  The proc need do little more than:

pascal void UserProc(dlog, item)
DialogPtr	dlog;
short		item;
{
	Rect	rect;

	GetDItem(dlog, item, &type, &hand, &rect);
	LUpdate(whatever it's args are);
	FrameRect(&rect);
}
