hsv_to_rgb, rgb_to_hsv - Converts color values between the HSV and RGB color spaces. Allegro game

       Convert color values between the HSV and RGB color spaces. The RGB values range from 0  to  255,  hue  is
       from 0 to 360, and saturation and value are from 0 to 1. Example:

          int r, g, b;
          float hue, saturation, value;
          ...
          /* Convert a reddish color to HSV format. */
          rgb_to_hsv(255, 0, 128, &hue, &saturation, &value);

          /* Now put our tin foil hat, and verify that. */
          hsv_to_rgb(hue, saturation, value, &r, &g, &b);
          ASSERT(r == 255);
          ASSERT(g == 0);
          ASSERT(b == 128);
