Review Request 115393: Add property to allow Dialog Popups to align to visualParent item's window

[David Edmundson]

This bug https://bugs.kde.org/show_bug.cgi?id=329199 has been open
since the 12th of December last year. You were even on the bug CC list
when I assigned it to me before I started working on it.

As for the widget explorer popups. I agree for a different reason.
License, Author and Email are completely useless pieces of
information. With my user hat on I don't care, and with my developer
hat on; this information is completely wrong 90% of the time. For
example Martin G is listed as the author of kickoff, despite being 5th
on git shortlog -sne.

That only leaves:
 - title, description and the uninstall button.
title and description we have on the delegate.

Which means we have a popup just for uninstall. Which is wrong.

With regards to this patch, is it still useful? I think it makes sense
as it puts all panel tooltips in the right place.
