    connecting the sites. If clipping planes are very expensive on your
    hardware this might be much faster. Also it's much uglier.
    (Actually I don't use clipping planes any more, so this is pretty moot.
    It gives _some_ preformance, but it's very marginal.)*/

   texture for the earth's surface. ( That is, load it into something like
   "xv", scale it down, and save it as PNG. )

/* Uncomment this one to get more realistic locations for satellites. The kind
   of sattelites used for this kind of thing are AFAIK all geostationary, and
   they are always over the equator. Since I don't _know_ where they are, I 
   make a guess. The default way to draw them is inaccurate in the sense that
   they don't neccesarily end up over the equator, but doing it this way means
   that sometimes the sat-ground line will go thru the earth, which obviously
   isn't correct either. */
