Real Resize Window

[OxyGeNe]

Hello, I've been searching a bit without finding anything really interesting, so I'm making this post. Does anyone have an idea for resizing a window? When I say resizing, I don't just mean the size/width, but really resizing its content as well. Kind of like a Windows preview.

You can make another window that captures screenshots from that application’s window, which would update at some rate (like a live thumbnail image), but you can’t resize the actual program window.
