How do I get the current location of a window?

[uerics@mcl.ucsb.edu (Eric D. Shepherd)]

As far as I can tell, there is no way to get the current X,Y position of
the upper-right hand corner of the window.  I want to be able to get that
position so that I can later feed it into MoveWindow (I'm writing a Finder
Extension, and want the window's position to be preserved between uses).

Any suggestions?
