Actually this is how I do it, and it's not so bad.  You seldom have more
than a half-dozen visible windows to look at.  (I don't even use its
PortRect, I just use its position and size.)

A wild suggestion with (possibly) no basis in reality is to try calling
find-view-containing-point and pass in nil as the view.  Various view
functions accept nil as a substitute value for the WindowManager, and this
might be a "super view" to all windows.
