inview.js outofbound check

[oliverfoster]

At the moment this doesn't quite work as something can be out of bounds but at the edge of the bounding rectangle.
This code:

            var isOutOfBounds = (childOffsetTop > parent.clientHeight
                || childOffsetLeft > parent.clientWidth 
                || childOffsetBottom < 0
                || childOffsetRight < 0);

should be inclusive of edge:

            var isOutOfBounds = (childOffsetTop >= parent.clientHeight
                || childOffsetLeft >= parent.clientWidth 
                || childOffsetBottom <= 0
                || childOffsetRight <= 0);
