Right now TabView fires "tabviewshow" and "tabviewhide" events to tell the Panorama UI frame to show/hide itself. It should just call into the frame directly, as these events confuse people looking at our API (who really want "tabviewshown" and "tabviewhidden").
Seems like something we should fix before extension authors dig in.
Unfortunately, we should punt on this.
