...and a few days later I found the Frame event which gives me the
GUIEventAdapter and GUIActionAdapter parameters I need to call
home (const GUIEventAdapter &, GUIActionAdapter &)
calling home(double) seems to work but doesn' t, finaly I also notized
that, after press "s" key to get the nice hud information about framerate
and modeldetails.
I hope now it realy works, not only seems to work :-)
