It isn't done one like that on Windows either, because the NVidia driver
is buggy and can not handle drawing into a window that belongs into a
different process (at least IMO that clearly is a video driver bug).
All you need to be able is:
1) Getting size and position of another processes' windows
2) Create and draw your own Window and keep it on top of that

2) is simplified on Windows by creating our own Window as a child window
of the -wid one, thus we do not need to handle position changes but only
resizes.
