 * Where does the call for is_visible() come from? I get a notice for an undefined
   funtion and see it getting called twice.

 * `Debug_Bar::init_panels()` and `Debug_Bar::render()` call `is_visible()` on all
   registered panels.
 * Normally a panel is a subclass of `Debug_Bar_Panel` which contains a default 
   implementation of `is_visible`
