            // area covers the path completely), then you should treat it as an empty set (no points
            // are included in the path). Then the current clipping path (which is the intersection
            // between previous clipping path and the new one) is also empty set, which means that
            // there is no visible content at all. But at the same time as we removed the clipping
            // path, the invisible content would become visible. So, to emulate the correct result,
            // we would simply put a degenerate clipping path which consists of a single point at (0, 0).
            Path degeneratePath = new Path();
            degeneratePath.moveTo(0, 0);
