If I add paths to a drawComponent and they overlap, the paths are stacked in the order they're added. I can add an event listener to each sprite so that it changes color and stroke width when I mouse over, but how do I bring the paths that are overlapped to the front? 

This is the set of listeners to change color:

```
listeners: {
    mouseover: function(line) {
        line.setAttributes({ stroke: "red", "stroke-width": 8}, true );
    },
    mouseout: function(line) {
        line.setAttributes({ stroke: "black", "stroke-width": 4 }, true );
    }
}

```
