/** @file gtk-lumiera.hpp
 ** The main application object.
 ** Invoking the GtkLumiera::main() function brings up the GUI; this
 ** function will block in the GTK event thread until the Application gets
 ** closed by user interaction or by triggering a shutdown via the GuiNotificationFacade.
 ** GtkLumiera is a singleton and owns the central WindowManager instance used for
 ** opening all windows and registering and loading icons and resources.
 ** 
 ** \par configuration and resource search
 ** The GUI object retrieves the necessary configuration values from lumiera::Config,
 ** the config facade in the application core. Currently as of 2/2011 these values are
 ** loaded from setup.ini, because the full-blown config system is not yet implemented.
 ** Amongst others, this configuration defines a <i>search path</i> for icons and a
 ** separate search path for resources. These path specs may use the token \c $ORIGIN
 ** to refer to the installation directory of the currently executing program.
 ** This allows for a relocatable Lumiera installation bundle.
 ** 
 ** @see guistart.cpp the plugin to pull up this GUI
 ** @see gui::GuiFacade access point for starting the GUI
 ** @see gui::GuiNotification interface for communication with the gui from the lower layers
 ** @see lumiera::Config
 ** @see lumiera::BasicSetup definition of the acceptable configuration values
 ** @see lumiera::AppState general Lumiera application main
