        public void paint​(java.awt.Graphics g,
                  int width,
                  int height,
                  int cellWidth)
        Render current mesh as a topographic map
        Parameters:
        g - Graphics context
        width - of the display map
        height - of the display map
        cellWidth - - pixels per cell This method uses the Marching Squares algorithm. for each topo line construct an over/under 2D bitmap march through the bitmap, summing neighbors use sum of neighbors to select an image
