============================================================================
[1.6] Supplemental example only (NOT USED by frigcal).
Demo the difference between iconify()/withdraw() on Linux and Windows.
On Linux, scripts must use withdraw() to get windows back with deiconify().
On Windows, either works, but withdraw() window doesn't appear in taskbar.
Linux also doesn't trigger <Unmap>/<Map> or <Configure> on minimize/restore.
