I'm afraid that I disagree -- ZoomWin should "zoom" onto the designated
window; its appearance should not change (other than size, of course).
You can see the difference visibility effect directly via the following
commands with vim:

What's happening:

* make two test files: file1, file2 that contain a difference
* use vimdiff to display both windows
* set hidden on one or both of the windows
* apply ":q" to one of the windows

You'll observe that the differences are still displayed.
