That's what I did in fact :). The function you are thinking about is
probably the one which is used by kwin effects to decide whether they
should for example show drop shadows below comboboxes. These effects
uses kwin API and are run by the kwin process. This is a bit different
in our case because we are outside the kwin process. Still, it would use
the same information kwin uses.
