// written July-August 2001 by Christoph Hormann <chris_hormann@gmx.de>
//
// demonstrates use of various new or changed features:
//
//    - isosurface (for the rail columns)
//    - mesh2 object (table cloth)
//    - uv-mapping (table cloth)
//    - pattern image type (background heightfield)
//    - slope pattern (background heightfield)
//    - variable reflection (water & glass)
//    - metallic reflection
//    - conserve_energy
//    - function pattern (water)
//    - fading interior (water, drink)
//    - 'circular' and 'orient' area_light
//    - radiosity
//    - photons (objects on the table)
