This is a means of instrumenting any pure-QML application to generate an
object diagram showing the items and related objects belonging to the
first top-level window that can be found.
Using a Timer for that is kindof crude; perhaps we should rather
have a separate WindowFinder object that can emit a signal when a
new top-level window is discovered, or something like that. Or use
a Shortcut to trigger it manually. But it works well enough for now.
