Thus, I'd consider an api for detecting the visibility state of every

This is pretty hard to implement, in general. For example, if I put
another window over the browser window then whether the content in the
browser is visible depends on the exact app running in that window, and
on the parts of it overlapping the browser content, right?
Sure. Some applications might even be partially transparent, like some
fancy-skinned media players.
Yes, that's precisely what I was saying above. And it's not just
"fancy-skinned media players". It's every single app on Windows 7 by
default (see "Aero glass"). It's a commonly tweaked setting for
Terminal on Mac. It's a common setting for terminal windows on Linux.
The fact is, at this point _most_ windows are partially transparent.
