// PHDStatusBar is a child of wxStatusBar and is composed of various control groups - properties of the guide star, info about
// current guide commands, and state information about the current app session.  Each group is managed by its own class, and that class
// is responsible for building, positioning, and updating its controls. The various controls are positioned (via the OnSize event) on top of the SBPanel that
// is the single underlying field in the base-class statusbar.  The SBPanel class handles its own Paint event in order to render
// the borders and field separators the way we want.
