[scribus] Shadow within a form

[Rolf-Werner Eilert]

I have 1.5.8 here and playing with the shadow tool, I was wondering if 
it is able to produce a shadow within a form.

This is useful to make a tablet-like form or something that looks like a 
bottle cap lying upside-down on the table.

Or maybe there is a trick?
