Can I ask why you want such an effect? It seems an odd way to scale a window to me. Normally you would want your screen layout to be locked in position.
I have had a go not sure if this is what you want. Bit of a bodge though.

Obviously it doesn't work with resizing the screen manually using the mouse, you would have to lock the window size to stop people doing that. Then use your own options. If IanM's matrix utils can give you the current window size rather than the screen size then you could use that to scale the sprite or object. I'm not sure if it has that function or not. Not used any dlls for a while.
