Widget visibility

Details

    Description

      X11 provides a mechanism for determining window visibility via VisibilityNotify event structure (XVisibilityEvent). In particular, the event returns a visibility state which can be any of: VisibilityUnobscured, VisibilityPartiallyObscured, or VisibilityFullyObscured.

      Having this kind of information available for a window (ideally even provide a visible region) would allow for some optimization.
