#include "config.h" /*
* The GIMP -- an image manipulation program
* Copyright (C) 1995 Spencer Kimball and Peter Mattis
*
* SphereDesigner v0.3 - creates textured spheres
* by Vidar Madsen <vidar@prosalg.no>
*
* Status: Aug 31 1999 - Messy source, will clean up later.
*
* Todo:
* - Editing of lights
* - Non-interactive mode
* - Saving / Loading of presets
* - Transparency in textures (preliminary work started)
* - (Probably more. ;-)
