Hi !

You don't have to set a palette unless you are in a palettized mode.
Doing so yields undefined results. You usually do

  if (GT_SCHEME(mode.graphtype) == GT_PALETTE) {
    ggiSetColorfulPalette(vis);
    ggiGetPalette(vis, 0, 1<<depth, pal);
  }

for programs that don't really care about the exact mode they run on.

To put colored pixels, you first do something like

  map[0].r=0xFFFF; /* this is the highest intensity value for the red part. */
  map[0].g=0xFFFF;
  map[0].b=0xFFFF;

  white=ggiMapColor(vis, &map[0]);

To obtain the pixel-value, which you can then use with the pixel arguments 
of ggiPut* and GCSet[Fore/Back]ground.

CU, Andy
