:   '''tkwait visibility''' ''name''

Waits for a change in the visibility state (as indicated by the arrival of a `<VisibilityNotify>` [event]) of window ''name''. This is typically used to wait for a newly-created window to appear on the screen before taking some action. Returns an empty string.

Note that this command is not particularly useful on non-[X11] platforms (Windows, OSX/Aqua) because `<VisibilityNotify>` events are never delivered. This is a platform limitation.
