Changes ======= New volumetric shadows for FlightGear. There is now two new checkboxes in the rendering dialog to enable/disable shadows for the user aircraft and for static scenery objects (ie those defined in the .stg files). AI and random objects are not handled for the moment. known bugs ========== - ghost objects
