Picasso96 PIP windows

[softwarefailure]

Is there a way to create PIP windows which are automatically moved when their "parent" is moved? I want to create a borderless PIP window that is part of a parent window. Whenever the user moves this parent window, the PIP window should be moved as well. Is there a convenient way to achieve this or do I have to move the PIP window manually whenever I get an IDCMP_CHANGEWINDOW message for the parent? But this would probably a very ugly solution...
