   Artists generating simulations for incorporation 
   into other graphics, e.g. land and skyscapes, 
   can find the horizon and other lines a nuisance.

   These can be suppressed in v3.1.2 onwards.   

   Go to 'Appearance' 'Visiibilty' on the main menu.
   Toggle the visibility of the horizon and boundary
   lines or the visibility of the sun.

   These adjustments must be made BEFORE the 
   simulation is started.  

   These options are NOT stored in the simulation
   parameter files.
