/* There are two types of window involved here. The first is the
* listener window. This is like the taskbar in Windows. It doesn't
* ever appear on-screen in our implementation, instead we create
* individual mini "adaptor" windows which are docked by the native
* systray host.
*
* In future for those who don't have a systray we could make the
* listener window more clever so it can draw itself like the Windows
* tray area does (with a clock and stuff).
