- * The ShellWindowTracker associates certain kinds of windows with

- * appear in places where we want to give a list of windows
- * for an application, such as the alt-tab dialog.
- *
- * An example of a window we don't want to show is the root
- * desktop window.  We skip all override-redirect types, and also
- * exclude other window types like tooltip explicitly, though generally
- * most of these should be override-redirect.
- *
- * Returns: %TRUE iff a window is "interesting"
