title: With JavaScript, can I change the Z index/layer of an SVG <g> element?
body: <p>Let's say I have a couple composite shapes (<code>&lt;g&gt;</code>).   I want to be able to click and drag them, but I want the one I happen to be dragging at the moment to be on TOP of the other one in the Z order, so that if I drag it over the OTHER one, the other one should be eclipsed.</p>
