Description
Changes in the method introduced in JDK-8153522

            int startX = (int)Math.floor(x * scaleX);
            int startY = (int)Math.floor(y * scaleY);
            int width  = (int)Math.ceil((x + w) * scaleX) - startX;
            int height = (int)Math.ceil((y + h) * scaleY) - startY;

potentially may cause IOOBE in
            System.arraycopy(srcBuffer, from, copyBuffer, from, width);
