This is intentional - only with very high effort (going far beyond what 
IMouse does today) it would be possible to retrieve the guest OS's 
opinion on the current mouse position. Only with guest additions 
(different for every guest OS family) this would be possible, and it 
would be a big effort to achieve something normal VM users wouldn't be 
interested in. You forgot to outline why you need this information...

Much cheaper is intercepting the mouse events going through IMouse, 
which can be done through the event source associated with IMouse.
