   I just strip all but the minimal sequences from ANSI file descriptions. I   
   could do something similar for ANSI in message bodies too, but I suppose   
   someone might be wanting to post animated ANSIs and want them to display as   
   intended.

   Do you translate the ANSI clearing and cursor movement sequence to a different   
   set of ANSI sequences or are you actually using the ANSI region definition   
   sequences to define this "message viewport" and letting the terminal handle   
   that?   
      
   I'm curious how absolute cursor positioning works when the coordinates are   
   outside of this "message viewport". Sounds like a lot of work and opportunity   
   for wonkiness. :-)   
      
    > Hope that helps clear things up.   
      
   Cool. So animated ANSIs actually display as intended (with the animation)? And   
   you can scroll up and down the message too? That'd I'd like to see. :-)   
      
   I'd up-vote your message, but... FidoNet. :-)
