* {@link #LAST_SUB_WINDOW}) are associated with another top-level
* window. For these types of windows, the {@link #token} must be
* the token of the window it is attached to.
* <li> System windows (ranging from
* {@link #FIRST_SYSTEM_WINDOW} to
* {@link #LAST_SYSTEM_WINDOW}) are special types of windows for
* use by the system for specific purposes. They should not normally
* be used by applications, and a special permission is required
