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).
