GUI elements

Do we have a tag for GUI elements like in post #424653? I think we have scroll_bar, but I can't find anything pre-existing to tag such a dialogue window with.

Edit: no, we don't apparently. I could've sworn we did.

There is a fake_scrollbar tag. If that's what you're thinking.

Though I don't recall anything with a gui. It's similar to the fake_screenshot... but I don't think that is quite right.

Desktop and windows are existing tags, though they pull in other things. (wallpaper, OS-tan)
