 * The base class for the SV main window.  This includes everything to
 * do with general document and pane stack management, but nothing
 * that involves user interaction -- this doesn't create the widget or
 * menu structures or editing tools, and if a function needs to open a
 * dialog, it shouldn't be in here.  This permits "variations on SV"
 * to use different subclasses retaining the same general structure.
