// the top-level actor be a Clutter.Group, which will accept
// the new width from the Sidebar, but not impose it on its

// any), separator line, and the expanded widget actor. (If
// the widget doesn't have a collapsed actor, and therefore
// supports pop-out, then it will also have a vertical line
// between the two groups, which will only be shown during
// pop-out.)

// In the expanded view, cgroup is hidden and egroup is shown.
// When animating to the collapsed view, first the ebox is

// we hide egroup, show cgroup, and slide cbox back in in the
