DESCRIPTION

16       A gouraud shaded polygon which interpolates RGB triplets rather than  a
17       single  color. In 256-color modes this uses the global rgb_map table to
18       convert the result to an 8-bit paletted color, so it must only be  used
19       after you have set up the RGB mapping table! The colors for each vertex
20       are taken from the `c' value, which is  interpreted  as  a  24-bit  RGB
21       triplet (0xFF0000 is red, 0x00FF00 is green, and 0x0000FF is blue).
